The first decision that needs to be made is what the final analysis will be for the analyte. This will have an impact on the sample and cartridge size, as well as the final elution solvent. Gas chromatography offers higher sensitivity than HPLC, while HPLC is better suited for ionisable species and very high molecular weights. If LC-MS is available, minimal sample clean-up may be required.

The ISOLUTE® family of cation exchange sorbents are used to extract organic cations (basic compounds capable of exhibiting a positive charge) from both aqueous and non-aqueous matrixes. Although extraction is by the same mechanism, each sorbent has properties that influence the way they are used.

Product Notes
In medicinal chemistry reactions are often carried out in solvents such as DMSO. Once the reaction is complete, it is usually necessary to separate the products of the reaction from reagents and by-products. This can be performed using strong cation exchange sorbents (e.g. ISOLUTE SCX-2 or ISOLUTE Flash SCX-2) to selectively isolate the basic compounds from the reaction mixture. (see Figure 1 for structure of ISOLUTE SCX-2 and ISOLUTE Flash SCX-2 sorbents)

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.

Question:
What is the maximum capacity of an SPE column?
Answer:
The capacity of a sorbent is defined as the total mass of strongly retained analyte that can be retained by a given mass of the sorbent under optimum conditions.
For most sorbents, this can range from 1-5% by weight. 100 mg of sorbent might retain 1-5 mg of analyte.
Ion exchange sorbents typically have a capacity of 0.3-1 meq/g.

ISOLUTE® SCX-2 is a propylsulfonic acid bonded sorbent used for the extraction of basic compounds from aqueous (or partially aqueous) samples using a strong cation exchange retention mechanism. It keeps a permanent negative charge across the pH range. Analytes are eluted from ISOLUTE SCX-2 by eliminating the charge on the analyte (high pH), so this sorbent is not suitable for extraction of strong bases. The sorbent is supplied in the protonated form.
ISOLUTE SCX-2 is the sorbent of choice when strong cation exchange is the primary retention mechanism, or if aqueous conditions are required for analyte elution. For methods listing PRS as the SPE sorbent, ISOLUTE SCX-2 is a direct replacement.
ISOLUTE SCX-2 is available in a wide range of SPE columns and 96-well plate formats.
