Solid phase extractionSPE is a chromatographic technique used to prepare samples for subsequent analysis by removing interfering substances that may be present. The general procedure includes sorbent activation,loading,washing and eluting. This is done either by retaining the substance of interest and washing off everything else or by retaining the interfering substances and eluting the product of interest. The vacuum SPE devices are designed to concentrate or isolate analytes from complex sample matrices.It allows processing of extration columns with high sample throughput at minimal expense.Solvents and samples are aspirated through the columns by a vacuum of 0-20 inches Hg.Eluates are collected in tubes positioned in a removables rack inside the mainfold.The 12-ports and 24-ports mainfold accommodate up to 12 and 24 columns,respectively.
