It is a very important step prior to analysis, otherwise the analyte signal could be suppressed by sample matrix interference. In most cases sample preparation entails some form of extraction of the analyte(s) of interest from the interfering species. Conventional extraction techniques include liquid-liquid extraction (LLE) and solid phase extraction (SPE). - Taken from introduction.636.51 KBPDFenAttribution (CC BY)chemical analysispolymer monolithsBook Chapter
