1 Columns Reduce Analysis Time; Reduce System Maintenance 0 YEARS Turning Visions into Reality

2 and Fused Silica Columns Detect and confirm 0 common organochlorine pesticides simultaneously. Complete analysis in less than minutes (see Figure ). Primary and confirmation analysis with one injection. Organochlorine pesticides represent a very common analysis in environmental laboratories, traditionally using Rtx -, Rtx -, Rtx -0, or equivalent columns. With traditional columns, however, it is difficult to resolve the 0 most commonly analyzed organochlorine pesticides in a reasonable time. Higher polarity columns also are problematic - they trap polar contaminants from the samples, and this reduces column lifetime. Rtx -CLPesticides and Rtx -CLPesticides columns were designed specifically for this application, with consideration for both analysis time and column lifetime. They separate commonly analyzed organochlorine pesticides rapidly, with high temperature stability that assures reliable data. Figure shows the analysis of 0 pesticides is completed in minutes - 0% of the time required on a traditional column! Further, an Rtx -CLPesticides column and an Rtx -CLPesticides column can be used under the same injection port pressure and oven temperature program, which makes them an ideal pair for dual column analysis. Some analysts prefer columns with internal diameters other than 0.mm, and Rtx -CLPesticides and Rtx -CLPesticides columns with other IDs can be used without sacrificing resolution. Figure shows these 0 pesticides exhibit the same resolution on 0.mm ID columns, in the same analysis time, as on 0.mm ID columns. To increase lab efficiency and throughput, Rtx -CLPesticides and Rtx -CLPesticides columns can be used under fast analytical conditions, reducing analysis time to less than minutes, as Figure shows. Column Deactivation Rtx -CLPesticides and Rtx -CLPesticides columns incorporate our proprietary intermediate polarity deactivation to make the tubing surface non-adsorptive to active pesticides. A second version of CLPesticides columns, Stx -CLPesticides and Stx -CLPesticides columns, incorporate our Siltek deactivation process, which makes the tubing surface virtually inert to endrin and other active compounds. These columns provide the ultimate performance for ppb on-column concentrations. Resolution on either column pair is not affected by the tubing deactivation. Additional Applications Laboratories strive to use one primary column / confirmation column pair for multiple methods, and Rtx -CLPesticides and Rtx -CLPesticides columns offer this convenience. In addition to organochlorine pesticides, compounds that are routinely analyzed by GC/ECD on these columns include triazine herbicides, chlorinated disinfection byproducts, haloacetic acids, and volatile chlorinated and brominated insecticides. Figures - demonstrate the versatility of Rtx -CLPesticides and Rtx -CLPesticides columns. tech tip A primary cause for downtime is system maintenance, to clean or replace contaminated injection port components. By using a "Y" connector to connect a guard column to an Rtx -CLPesticides / Rtx - CLPesticides column pair, one injection port and one injection of sample extract can be used for the primary and confirmation analysis. This cuts injection port maintenance by half, which greatly reduces downtime. injector guard column SeCure Y connector analytical columns detectors
