Extraction is required during sample analysis when filtration does not yield optimal results in sample preparation. The aim is to selectively “extract” the substances to be analysed from the sample. There are two methods: Liquid-Liquid Extraction (LLE) and Solid Phase Extraction (SPE). Another method to extract pesticides is QuEChERS (Quick Easy Cheap Effective Rugged Efective Safe), which is based on a combination of LLE and SPE. Here you will find devices & accessories for solid phase extraction (SPE) from all well-known manufacturers such as Agilent, Merck Millipore, Thermo Fisher and many more. You will also find a great selection of SPE cartridges in our shop.
