Column set saves time and money for chlorinated pesticide testing commonly performed by environmental and drinking water testing labs, which often need to run up to seven EPA methods on a single instrument. To carry out this testing, labs typically need to perform multiple, time-consuming column changes which negatively impacts productivity. The Zebron ZB-CLPesticides GC-1 and 2 column set, which contains two phases with orthogonal selectivities specifically optimized for pesticide analysis, runs all seven methods. These new columns expand the Phenomenex Zebron family of products for GC pesticide testing, which also includes ZB-SemiVolatiles and ZB-MultiResidue-1 and 2. Phenomenex
