Application Note: Challenging Pesticide Analysis Using An Agilent J&W DB-35ms Ultra Inert GC Column

As the world population has grown so has pesticide use to protect crops and increase crop yields. Traces of these pesticides are present in the food supply and the effect of long term exposure to these materials is not well understood. Interest in monitoring pesticide levels in soil, water and food matrices has risen with increased use of pesticides and the availability of highly sensitive analytical equipment.

This note shows the fast and effective separation of both organochlorine and organophosphorus pesticides using an Agilent J&W DB-35ms UI 20 m × 0.18 mm, 0.18 µm column (Agilent p/n 121-3822UI). Peaks known to coelute on a 5% phenyl phase are shown baseline-resolved on an Agilent J&W DB-35ms UI column. Peak shapes were consistently excellent and remained so when spiked into a complex fish tissue sample matrix.
