  Do you still feel tired about complicated and time-consuming sample preparation? In pursuit of more efficient and faster sample pretreatment, Welch launched a new generation of product- SinCHERS pretreatment purification column.  Compared with traditional SPE technology, SinCHERS column greatly improved detection efficiency. Compared with the QuEChERS, its purification process does not require centrifugation again and only need one step (30s) to complete the purification process. The development of electric supporting equipment enables the whole purification process to be semi-automated. The purification of 12 samples can be completed within 3 minutes, which greatly improves the detection efficiency and relatively reduces the detection cost of the laboratory.
