Agilent J&W CP-Sil 19 CB for Pesticides columns are designed for the analysis of pesticides, particularly EPA and CLP analytes. Not only do they possess less bleed than a standard polymer, which improves the signal-to-noise ratio and minimum detectable quantities, but they also have higher upper temperature limits which allow for faster run times. The columns are supplied with a coupled retention gap for on-column injections for best detection limits.
