J&W Scientific low bleed columns are ideal for the analysis of pesticides. 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.
(14%-Cyanopropyl-phenyl)-methylpolysiloxane (Low/midpolarity; exact replacement of HP-PAS1701). Specifically designed and processed for the analysis of organochlorine pesticides. ECD tested to assure minimal pesticide breakdown and low ECD bleed. Bonded and cross-linked. Solvent rinsable.
