Columns for Sapmle Clean-up

The CLNpak^® series are pretreatment columns packed with rigid polymer-based gel. Target sample is cleaned up from a complex matrix in size exclusion (SEC) mode.

EV	· For the separation od residual pesticides in food · Adopted as the purification method in tast solution preparation in Notification No.1003001 of The Dept. of Food Safety, MHLW, Section 2 "Simultaneouws GC/MS (LC/MS) Analysis of Agricultual Chemicals in Livestock and Marine Products"
PAE	· Fot the clean-up of samples in water-rich matrix such as blood and bottom sediment · Highly effective in the separation of endocrine disruptors in environmental samples
