Step By Step Guide To SPE Method Development
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.

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.
Browse more questions and answers >Typical Applications:
- Polar organics
- Acid herbicides
- Explosives
- Phenols
ISOLUTE® ENV+ is a high purity, hyper cross-linked polystyrene based polymeric sorbent with a hydroxylated surface, capable of extracting a wide range of polar, water soluble analytes from aqueous samples. Its high surface area and optimized pore structure make it ideal for extraction of very polar analytes, such as phenols and acid herbicides.
Structure of ISOLUTE® ENV+ sorbent
ISOLUTE® ENV+ has a very high capacity for polar compounds (up to 50% by weight for caffeine) reducing analyte breakthrough and improving recovery for even the most polar of compounds. It is totally water wettable, so it will never become de-conditioned, even if it runs dry. Columns do not need to be stored in solvent after use.
Biotage ISOLUTE® ENV+ On-line Cartridges combine these unique sorbent characteristics with the convenience of fully automated SPE.
Sorbents and columns are fully QC tested to ensure excellent performance and reproducibility.
Biotage on-line SPE columns can be used with most commercially available on-line SPE systems.
See technical note PS424 for more information.
