For simultaneous pretreatment of various type target compounds from complex samples, highly efficient analytical instrumentation has been developed, such as GC-MS, HPLC-MS-MS, CE-MS, and so on.However, because the complexity of sample matrix, sample preparation is a key stage and an essential step in the whole analytical process, it most included: extraction, cleanup, and concentration, and the every step is time-consuming.By some estimates, about 60-80% of the work in an analysis is spent on preparing samples.
