This application note was developed for the clean-up of a non-polar solvent extract of vegetable material. The methodology is applicable to a wide range of organochlorine and organophosphorus pesticides and a number of vegetable types. The analytes are relatively non-polar, and will not be strongly retained by polar/anion exchange sorbents.

The use of schedule I drugs for patient pain management therapy warrants constant monitoring of therapeutic levels in the patient. Screening patient urine samples for the free drugs is complicated by the metabolism process which converts the free drug to the -glucuronide form. Patient urine samples can be enzymatically hydrolyzed to cleave glucuronide moiety and produce the free form of drug. The target analytes can them be extracted from the urine matrix using EVOLUTE CX solid phase extraction cartridges.

This application note describes the extraction of several peptides, ranging in size from a 7mer to a 54mer, from plasma and serum using EVOLUTE® ABN in a 96-well plate format. The presence of certain proteins and peptides in human biological matrices can be used as diagnostic markers for the onset of disease and other health problems in humans. The ability to detect and monitor lower levels of peptides can aid in clinical patient health assessments and therapeutic drug level determinations. The sample preparation methodology detailed in this application note can significantly increase sensitivity and detection of peptides from biological matrices on LC/MS/MS. This application note offers the user two different elution strategies due to the extensive combination of peptides that may need to be extracted either strategy may be suitable dependent upon which peptides are relevant.

This method was developed for the extraction of phencyclidine from meconium for drugs ofabuse applications. The analyte has an ionisable amine group, which is exploited through cation exchange interactions. The pKa is approximately 8, so the compound is fully ionized at pH values of less than 6. The analyte also has significant non-polar characteristics, and both hydrophobic and ion exchange retention mechanisms are used to give a clean extract.
