Unique Rtx®-CLPesticides Column Set Provides Optimal Results for Organochlorine Pesticides GC-Micro-ECD Analysis Using Any Carrier Gas

5 Nov 2014

Over the past few years, the increasing costs and uncertain availability of helium have prompted many labs to explore alternate carrier gas options. This application note compares the performance of Rtx®-CLPesticides and Rtx®-CLPesticides2 columns to a competitor’s CLP column set using helium, hydrogen, and nitrogen carrier gases for a frequently used dual-column GC-ECD method. These column sets differ in selectivity, and since proprietary Rtx®-CLPesticides and Rtx®-CLPesticides2 columns were developed specifically for organochlorine pesticides analysis by GC-ECD, their unique column selectivities provide optimal resolution and fast analysis times whether operated using helium, hydrogen, or nitrogen carrier gases.

Gas ChromatographyGas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors. Find the best gas chromatographs in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Gas Generators and AnalyzersGas generators are used for supplying or monitoring a regular flow of a high purity gas such as nitrogen, hydrogen or zero air for applications such as gas chromatography. Gas analyzers can be used in supply chain processes and laboratory experiments with portable analyzers for monitoring CO<sub>2</sub> and O<sub>2</sub> levels as well as trace gases. Regular flow can be produced with gas control modules and flow meters.

Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity.  Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Carrier GasPesticidesPesticides are used to protect crops from diseases, pests and unwanted plants. They are classed as persistent organic pollutants (POPs) and can be harmful to humans. The Environmental Protection Agency (EPA) currently regulates the use of pesticides in the USA.
