Agilent J&W VF-1701 Pesticides is specially designed for the determination of trace levels of pesticide residues. Every column is individually tested before shipment with key pesticides, including endrin and aldrin, ensuring optimal performance and consistency of results. The columns are highly inert for trace pesticide determination, and therefore provide better detection limits. Analyses at extremely low concentrations are easy, regardless of whether the method specifies ECD or MS detection. VF-Pesticides columns benefit from ultra-low-bleed technology to improve sensitivity.
