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.

Method Development Guidelines: Solid Phase Extraction Using Polar, Silica Based ISOLUTE® SPE Sorbents for the Extraction of Non-Aqueous Samples
The ISOLUTE® family of polar sorbents are used to extract polar organic compounds from non-polar matrixes.
There are many functional groups that can exhibit polar interactions, and they have different selectivities.Some of the polar interactions that exist include dipole-dipole,dipole-induced dipole and hydrogen bonding. Polar interactions are particularly useful for the separation of molecules that are very similar in structure (e.g. structural isomers.

Q&A
SPE column capacity
01 July 2013Question:
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® PSA is an ethylenediamine-n-propyl bonded sorbent sorbent used for the extraction of strongly acidic compounds (e.g. those containing sulfonic acid groups) or analytes unstable under acidic conditions, from aqueous samples using a weak anion exchange retention mechanism. It can also be used to complex with certain metal cations. Analyte elution can be performed by neutralizing charge on the sorbent (high pH). The sorbent is supplied as the free base.
Alternatively, ISOLUTE PSA can be used for extraction of polar compounds from a non-polar matrix using a hydrogen bonding retention mechanism. It is less retentive than ISOLUTE SI.
ISOLUTE PSA is available in a wide range of SPE columns formats.
ISOLUTE PSA is also available as loose sorbent (100g pack).
