Pesticide analysis remains the largest environmental application for packed columns. Currently, mixed phase packed columns do not offer complete resolution of chlorinated pesticides, and require long analysis times （nearly 40 minutes）.
Restek has developed a special packing material that exceeds EPA Method 608 resolution requirements while delivering a faster analysis time than any other pesticide phase packed column available. Inert SilcoSmooth® tubing and highly inert Silcoport® support make it possible to analyze chlorinated pesticides at levels below 50pg—performance that is nearly impossible with older packed column technology. The computer-modeled phase resolves all 18 peaks in US EPA Method
