This Chemistry Data Sheet includes specifics on the use of ISOLUTE 101 for the extraction of polar analytes from aqueous samples (page 1), ordering information (page 2) and a general discussion on non-polar sorbents (appendix page 3).
Laboratory chemica Not for therapeutic or diagnostic use
This method is recommended for the extraction of oligonucleotides from aqueous synthesis mixtures using a non-polar retention mechanism. See General Comments for more details on how this works.
This method is suggested for the purification (de-salting) of aqueous peptide synthesis mixtures using ISOLUTE 101 non-polar columns. See General Comments for details on how this approach works.
This method is suggested for the simultaneous extraction of acidic, neutral and basic compounds from postmortem tissues, blood and urine. The retention mechanism is hydrophobic.
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.
