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.

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.

ISOLUTE HAX mixed-mode SPE sorbent is based on a combination of strong anion exchange and non-polar chemistries. Acidic drugs are retained by two primary retention mechanisms. This allows a rigorous interference elution regime to be used to elute interferences retained by either non-polar or anion exchange interactions alone. Only analytes with both non-polar and acidic characteristics are extracted usign the ISOLUTE HAX sorbent, providing an extremely pure final extract.

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 >
