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.

This poster describes a strong cation exchange SPE protocol for extraction of Vitamin B3 (Niacin) and related metabolites from serum.
The ISOLUTE SCX-3 96 well plate format demonstrated as a viable option for serum measurements over a relevant concentration range in clinical diagnostics.
It is anticipated that strategies presented in this poster would be of broad-based interest to clinical laboratories focused on combining parent/metabolite assays into a single analysis.

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.

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.

What is the maximum capacity of an SPE column?
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.Browse more questions and answers >
