Systems, devices, and materials for solid phase extraction (SPE) of analytes from complex liquid or solid matrices, using various sorbents and techniques, in preparation for chromatography; for a variety of sample sizes and types, and formats.
Supelclean ENVI-18 SPE tube is used for reversed phase separations involving a polar (usually aqueous) or moderately polar sample matrix (mobile phase) and a nonpolar stationary phase.
Get improved analysis of drugs of abuse, including basic and neutral drugs, with these SPE cartridges featuring both nonpolar and ionic separation characteristics.
Obtain excellent retention of drugs, metabolites and structural isomers with these aminopropyl SPE cartridges that allow both polar and anion exchange interactions.
