    USE OF BONDED PHASES FOR SAMPLE P REPARATION

    CONDITIONING, SOLVATION (WETTING)

    Columns are shipped dry, but those with hydrophobiccharacter need to be solvated in order to interact efficientlyand reproducibly with aqueous matrices. Sample capacity isseverely reduced on a dry column.

    At low vacuum ( - 3 in. Hg) add 1.5 mL of methanol or aceto-nitrile per 100 mg of sorbent to the sample preparation col-umn. Release the vacuum or begin flushing immediately uponcompletion. The more air which passes through the columnbefore sample loading, the less solvated the sorbent will be.

    Apply deionized or distilled water to remove excess solventwhich will interfere with hydrophobic binding. Use 1 mL H2Oper 100 mg sorbent. Momentary high vacuum (5 to 8 in. Hg)may be necessary to restart flow. At - 2.5 in. Hg the column

    will resist air displacement (vacuum may be left on withoutdrying the sorbent). If the sorbent is accidentally dried, resol-vate and reflush.

    When using ion exchange columns, apply 1mL of buffer tothe column after flushing to ensure that the sorbent pH isoptimal for the sorbent analyte interaction desired. Whereion exchange interactions are involved, follow guidelinesconcerning pKa, pH and ionic binding. Use the same vacuumguidelines as described for flushing.

    When doing work where a very clean baseline is requiredwashing the column with the elution solvent as part of theconditioning step will improve the LOD and LOQ.

    SAMPLE PREPARATION AND APPLICATION

    Mechanisms may be hydrophobic, polar, or ionic. Add internalstandard to the sample if quantitation is desired. Optimizesample application by removing particulates if necessary(centrifugation or filtering) and/or diluting viscous matriceswith water or buffer to ensure proper pH for desired inter-actions. The analyte and sorbent should be uncharged foroptimum hydrophobic retention. On ion exchange sorbents,analytes must be oppositely charged to the sorbent [anions(-) on anion exchange sorbents (+); cations (+) on cation ex-change sorbents (-)]. During sample application, the analytebinds by displacing a counterion on the sorbent.

    Apply sample at a rate of 1mL/min. Again, a momentary

    increase in vacuum may be needed to initiatesample flow.

    WASHING THE SORBENT AND ELUTING

    Ideal washing removes as many interferences as possiblewhile retaining the analyte(s). Ideal elution recovers 100% ofthe analyte while leaving behind interferences. Make certainyour column is dry when changing between aqueous solu-tions and organic solvents.

    HYDROPHOBIC AND POLAR ANALYTES

    The best approach towards using these types of sorbents isto search for a solvent mixture which will wash the most inter-ferences from the sorbent without loss of analyte. Note thatwash pH may greatly affect cleanup and/or recovery. Keepanalyte and sorbent pKa in mind if applicable. Elute with thestrongest organic solvent, or by raising the percentage oforganic, possibly in combination with a pH change to disrupt

    binding.

    ION EXCHANGE

    Ionic bonds are strong enough to allow the analyte to remainbound while interferences are washed away with high per-centages (up to 100%) of polar or nonpolar organic solvents.The pH will also affect sample cleanup. Remember to remain2 pH units from the relevant pKa of your analyte and sorbent,both of which need to remain charged for ionic retention.Elute with aqueous buffers containing a stronger counterionthan your analyte (classic ion exchange) or by changing pH todisrupt the ionic attraction. Make sure the elution solvent hasenough organic character to overcome any adsorption due to

    the packing material.

    COPOLYMERIC EXCHANGE

    For ionically bound analytes, use washes of high organicstrength to remove interferences retained by hydrophobic(solvent strength dependent) interactions. If your analyte isalso capable of hydrophobic binding, remove polar interfer-ences ionically similar to your analyte by using aqueous orweak aqueous/organic washes while disrupting ionic (pH andionic strength dependent) binding. Elute by simultaneouslydisrupting ionic and hydrophobic interactions

    MECHANISM OF CLEAN SCREEN

    Sample ApplicationWhen a sample is loaded onto the column at pH 6, many carboxylicacid functionalities present in the sample are ionized. This creates arepulsion between the column and many sample borne interferences,thereby reducing the likelihood of their adsorbing onto the column.At this pH, ibuprofen & barbiturates are not i onized and arehydrophobically adsorbed on to the column (figure 1). At the sametime, drugs with amine functionalities such as cocaine andphencyclidine adsorb on to the column via both hydrophobic andionic attraction (figure 1).

    The column can then be washed with water or weak aqueousbuffers at or below pH 6 without risking loss of the analytes. Afterdrying the column, it is possible to elute the hydrophobically boundanalytes using solvents of minimal polarity such as methylenechloride or a hexane/ethyl acetate mixture (figure 2). Cationic

    analytes will remain bound to the column. Many compounds ofintermediate polarity and potential interferences will also remainon the column. The majority of these potential interferences canbe removed by using a methanol wash.

    Cationic analytes bound to the column can be eluted after anotherdrying step. The drying steps are necessary to remove water whichwould have prevented the water immiscible elution solvents fromoptimally interacting with the analytes (figure 3).

    To elute the cationic analytes, an organic solution with a high pHshould be used. A methylene chlorideisopropanol-ammoniumhydroxide mixture will simultaneously disrupt these ionic

    interactions and successfully elute the desired compound (figure 4).

    CLEAN SCREEN

    COPOLYMERIC BONDED PHASES FOR DRUG ABUSE TESTIN

    Analytical demand for more efficient, robust and clean extraction of drugs from biological matrices led to thedevelopment of CLEAN SCREENsorbents. Since 1986, CLEAN SCREENhas led the industry with dependableand reproducible Solid Phase Extraction products and applications. CLEAN SCREENphases are true copolymericsorbents that contain hydrophobic and ion exchange functional groups uniquely polymerized to a silica substrate.The design and quality of CLEAN SCREENprovides superior sample clean up, recovery and reproducibility.

    Mixed mode separations allow maximum selectivity for extraction of acids, neutrals and bases. This selectivitymakes CLEAN SCREENideal for both screening and confirmation analysis for virtually all drug categories.CLEAN SCREENcolumns are used extensively by forensic and clinical chemists including:

    The small polar nature of the molecule and the lack of a UV chromatophore complicate the chromatographic andspectrophotometricanalysis of GHB. Chemically, GHB is unstable and readily forms Gamma-butyrolactone when heated inacid conditions. Most analytical methods are based upon the interconversion to the lactone and chemical derivatization to

    form the TMS derivative. This column is for the extraction of free GHB.

    CLEAN SCREENBNZ

    columns are available forbenzodiazepine extractions,with specific focus on7-amino benzodiazepines.

    CLEAN-THRU tips provides the first solid phase extraction cartridge system that eliminates sample carry overfrom the vacuum manifold lid. The technology was pioneered by our research scientists & consists of one of ourSPE columns with a disposable tip that attaches to the end of each column. Columns available in the CLEAN-THRU configuration are found in the CLEAN SCREENsections. This system was designed in order to meet the strictrequirements that the Substance Abuse and Mental Health Services Administration certification has placed on labo-ratories to address the problem of cross contamination between samples. CLEANTHRUtips provide a completely

    disposable system that eliminates any contact between the sample, wash solvents and the extraction apparatus.The continuous passage of the sample through the system provides a direct, accurate route to waste or collectionvessels. As each extraction is completed, the column and tip are discarded as a unit. CLEAN-THRUeliminates yourconcerns about sample residue remaining in the extraction system.U CLEAN SCREENsorbent as well as otherphases are available in this larger particle size.

    CLEAN-UP

    HYDROPHOBIC EXTRACTION COLUMNS

    This sorbent is composed of a silica backbone bonded

    with hydrocarbon chains. It is used to extract compounds

    which exhibit non-polar or neutral characteristics out of

    complex matrices. The C18 phase is the most widely used

    for non-polar interactions because of its nonselective nature;

    C18 will extract a large number of compounds with differing

    chemical properties. To enchance selectivity, UCT offers a

    wide range of hydrophobic sorbents. Multiple chain configu-

    rations are available for some Endcapped or unendcapped

    sorbents are available for all chain lengths.

    CLEAN-UP

    HYDROPHOBIC EXTRACTION COLUMNS

    MECHANISM OF HYDROPHOBIC BONDING

    Compounds are retained by non-polar interactionsfrom polar solvents or matrix environments. They are

    bound by dispersion forces / van der Waals forces.Elution, or disruption of the non-polar interactionsis achieved by solvents or solvent mixtures with suf-ficient non-polar character. Some polar solvents, suchas acetonitrile have enough non-polar characteristicsto disrupt nonpolar binding to cause elution of acompound from the sorbent. Methanol can be usedas well, although it should be noted that it will takeoff both polar and nonpolar analytes of interest andinterferences.

    UNENDCAPPED VS. ENDCAPPED

    Bonded phases are manufactured by the reactionof organosilanes with activated silica. During thepolymerization reaction of carbon chains to the silicabackbone, a very stable silyl ether linkage forms. Ourunendcapped columns allow hydroxyl sites to remain,thus making these columns slightly hydrophilic.

    In order to decrease this slight polarity, thesehydroxyl sites are deactivated. Proprietary bondingtechniques ensure that these sites are 100% reacted,leading to a complete endcapping. Because thereare no hydroxyl sites left, our endcapped columnsare more hydrophobic than our unendcapped columns.

    Mechanism of

    Hydrophilic Bonding

    Compounds are retained on hydrophilic

    sorbents through polar interactions including

    hydrogen bonding, pi-pi or dipole-dipole

    interaction. These types of interactions

    occur when a distribution of electrons

    between individual atoms in functional

    groups is unequal, causing negative and

    positive polarity. Compounds typically

    extracted on a hydrophilic column include

    analytes which have polar groups,

    including amines, hydroxyls and carbonyls.

    Elution is performed by strong polar solvents.

    UThis sorbent is composed of a silica back-bone bonded with a carbon chain terminatedby a negatively or positively charged functionalgroup. Ion exchange interactions occur be-tween a sorbent that carries a charge anda compound of opposite charge.

    This electrostatic interaction is reversibleby neutralizing the sorbent and /or analyte.Ion exchange bonds can also be disruptedby introduction of a counter ion to com-pete with the analyte for binding sites onthe sorbent.

    MECHANISM OF ION EXCHANGE BONDING

    Compounds are retained on the sorbent through ionic bonds. Therefore, it is essential that the sorbent and theanalyte to be extracted are charged. Generally, the number of molecules with charged cationic groups increasesat pH values below the molecules pKa value. The number of molecules with charged anionic groups decreases atpH values below the molecules pKa value. To ensure 99% or more ionization, the pH should be at least two pHunits below the pKa of the cation and two pH units above the pKa of the anion. Elution occurs by using a solventto raise the pH above the pKa of the cationic group or to lower the pH below the pKa of the anion to disruptretention. At this point, the sorbent or compound will be neutralized.

    This sorbent is composed of a silica back-

    bone with two types of functional chains

    attached - an ion exchanger or polar chain

    and a hydrophobic carbon chain. Our

    copolymeric phases are produced in a way

    to allow for equal parts of each functional

    group to attach to the silica backbone. Thiscopolymerization technique yields reproducible

    bonded phases and unique copolymeric

    chemistries which allow the controlled use

    of mixed mode separation mechanisms.This

    type of dual chemistry is beneficial especially

    when one is looking for both a neutral &

    charged compound. This is common when a

    neutral parent drug metabolizes & becomes

    a charged compound.

    MECHANISM OF COPOLYMERIC BONDING

    Using a sample composed of a theoretical neutral parentdrug and its charged (acidic) metabolite, it is appliedat a pH of 6 (figure 1). At this pH, many amine groups are

    positively charged. Since the column is also positivelycharged, compounds with this chemistry (cations)are repelled. Depending on the pKa of the metabolite,carboxylic acid groups may be negatively charged, allowingthe metabolite to bond to the positively charged sorbent.Since the column also possesses a hydrophobic chain,the neutral parent drug also bonds to the column.

    Water or a weak aqueous buffer (pH6) washes awayhydrophilically bound interferences (figure 2). The columnis then dried, careful to free the column of any residualaqueous phase that would interfere with elution.

    COVALENT EXTRACTION COLUMNS

    COVALENT

    Covalent sorbent has aldehyde functional groups that are bound to the silicabackbone by a hydrocarbon chain. The aldehyde group will react selectively

    with compounds containing a primary amine. A formal bond is createdbetween the stationary support and the primary amine containing material.

    MECHANISM OF COVALENT BONDING

    The primary amine in the sample performs a nucleophilic attack on the aldehydefunctional group attached to the support. This results in a Schiff base, with theamine immobilized on the stationary support. This chemistry can be utilized tobind proteins, such as antibodies, to the support, allowing highly specific extractions.

    STYRE SCREEN

    POLYMERIC RESIN EXTRACTION COLUMNS

    Styre Screenextraction columns contain an ultra clean, highly cross-linked styrene and divinylbenzene copolymersorbent that is functionalized with both a reverse phase, hydrophobic component and a strong cation exchanger.High and reproducible recoveries for acidic, neutral and basic compounds are achievable with a single column. TheStyre Screenparticles have an average particle size of 30 microns and a very high analyte capacity making them idealfor standard solid phase extraction applications. The increased analyte capacity means that less sorbent bed mass isneeded which results in faster flow rates and less solvent use. Higher throughput and less solvent waste disposal

    translate into significant savings in both time and money. In addition, no conditioning steps are required for mostdrugs of abuse applications.

    SOLID PHASE EXTRACTION COLUMN METHOD DEVELOPMENT KITS

    UCT understands that the optimum

    sorbent for any given separation

    cannot always be chosen empirically

    and that the cost of purchasing

    individual sorbents for screening

    purposes can be prohibitive. We offer

    the following kits at prices designed

    to reduce the cost of assay development:

    Non-Polar Phases

    Polar Phases
