Pesticide Residue Analysis

Environmental Testing Laboratory utilizes current FDA PAM, EPA and AOAC methodologies for its pesticide analysis. These, coupled with our internal Standard Operating Procedures (SOP), adherence to the Chain of Custody for all samples from sample collection to analysis, the use of high quality, high purity analytical standards, utilization of quality equipments such as gas chromatographs (GC), high performance liquid chromatographs (HPLC) and mass spectrometers (MS), ensure accurate and reproducible analysis. 

The equipment used by Environmental Testing Laboratory is configured for the detection of organochlorines, organophosphates, organonitrates, organosulfates and methyl carbamates. Based upon the extraction methods and equipment utilized, well over 250 compounds as listed, in the FDA's Pesticide Analytical Manual Volume I Table 302-A, can be analyzed for and recovered by ETL lab. Utilizing all of the above and employing highly qualified, well-trained and dedicated personnel assures that the client obtains accurate and timely analytical results.
