Preliminary (5-Batch) Analysis is a central requirement for pesticide registration in the agrochemical industry. Five or more production batches of a potential pesticide are analyzed for the amount of active ingredient present and to identify and quantify any impurities. At EPL, all 5-Batch analyses are performed in a timely and precise manner in compliance with US EPA GLP standards. EPL has conducted 5-Batch analyses on over 50 active ingredients in its 20 years of service.
