ISOLUTE® Layered SPE columns are designed for efficient extraction of multi-analyte suites. Layers of different SPE sorbents are contained in a single SPE column, enabling a broader range of analytes to be extracted than with a single sorbent.
This technical note describes the use of layered SPE columns in applications where multiple suites of analytes with a broad polarity range are to be extracted simultaneously from a single water sample, such as organochlorine, triazine and organophosphate pesticides, or endocrine disrupters.

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.

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.

Samples containing multiple analyte suites of very different chemical characteristics can be efficiently extracted using layered columns. This means that a single sample can be collected and extracted in order to determine multiple analyte suites, whereas separate samples would be needed if more than one extraction column was required. The layered column approach can significantly reduce costs and improve productivity.
Depending on the polarity range of analytes to be extracted, columns with different layers are available.
