Sample preparation techniques such as protein precipitation, supported liquid extraction or non-polar SPE may not be selective enough to give extracts of sufficient purity for low level analysis. In these cases, the selective mixed-mode approach to the extraction of basic and acidic drugs is a suitable alternative, giving very high purity extracts with minimal levels of co-extracted material.

Non-polar SPE is commonly used for extraction of acidic, neutral and basic drugs from biological fluids. It is particularly useful when a parent drug and metabolites of different functionalities are to be extracted simultaneously, and will provide cleaner extracts than alternative sample preparation techniques such as protein precipitation.

Protein precipitation is a routinely used sample preparation technique for removal of proteins from biological fluid samples prior to analysis. Protein precipitation in the 96-well format, using filtration for protein removal, is a high throughput alternative to the traditional centrifugation based technique.

ISOLUTE® Si-Propylsulfonic acid (SCX-2) belongs to a class of strong supported acids. As a bound sulfonic acid, it has a natural propensity to bind alkali and some transition metal group metals, which means that it can be used as a scavenger for metals with a +I or +II oxidation state, such as Na, K, Li, also
Pd, Rh, and Ru.

ISOLUTE® Si-Trisamine is a silica bound equivalent of a trisamine base and can scavenge a variety of electrophiles, including aldehydes, acid chlorides, sulfonyl chlorides, isocyanates, isothiocyanates and heavy metal ions such as Mn2+, Fe3+, Co2+, Ni2+, Cu2+, Pb+2, Ru+2 and Zn2+.

ISOLUTE® Si-Propylsulfonic acid (SCX-2) belongs to the class of strong acids. Similar
to ISOLUTE Si-TsOH (SCX-3)1, it can be used to (a) scavenge amines and other bases such
as anilines and borohydrides (b) as an acid catalyst in reactions or (c) as a replacement
for aqueous or organic acids in quenching reactions. The advantage of using SCX-2 as a
bound acid reagent is in that it eliminates work-up. The crude reaction mixture can be evaporated to dryness and the resulting free flowing solid can be purified directly by flash column chromatography.

ISOLUTE® Si-Thiol is the silica-bonded equivalent of 1-propanethiol, which is useful
for covalent scavenging of alkyl, benzyl, and allyl halides as well as a variety of other
electrophiles including acid chlorides and isocyanates. In addition it can be used to
scavenge a variety of metals1 used in organic synthesis including Pd, Pt, Cu, Hg, Ag and Pb.

ISOLUTE® Si-TsOH (SCX-3) is the bound equivalent of p-toluene sulfonic acid with a
pKa <1. Similar to ISOLUTE propylsulfonic acid (SCX-2)1 , it can be used to (a) scavenge
amines and other bases such as anilines and borohydrides (b) as an acid catalyst in reactions
or (c) as a replacement for aqueous or organic acids in quenching reactions.
