In this application note, a suite of neutral and list 1 pesticides in methylene chloride is evaporated using the Biotage® DryVap.
Pesticides containing many different functional groups, including sulfur and phosphorus groups, halides, nitramines, atrazines, alcohol, and carbonyl groups were efficiently concentrated for GCMS analysis.
This data indicates that the DryVap System is inert and effectively manages solvent evaporation without generating localized hot spots in the system.

EPA Method 608 describes the procedure to determine low parts per billion levels of organochlorine pesticides, polychlorinated biphenyls, toxaphene and chlordane in wastewater. The laboratory that collected the data presented in this application note uses EPA method 608 ATP3M0222 as the approved SPE technique for waste water extraction.
The disks compared in this study are : “Certified for Automation” Atlantic™ C18 (47 mm) and 3M Empore™ High Performance Extraction Disk C18 (47 mm). Comparisons were made using side-by-side extraction and identical calibration parameters.

The City of Fort Worth, Water Department conducted an evaluation of the Atlantic™ solid phase extraction (SPE) C18 disks using EPA Method 608. This application note describes the procedure to determine low ppb levels of organochlorine pesticides and PCBs in wastewater. This procedure used methylene chloride as the primary extraction solvent, followed by a hexane solvent exchange. Extracts were then analyzed by GC/ECD using a pressure pulse injection technique.

The initial use of many chlorinated pesticides, herbicides, and organohalides were to aid humanity. DDT was created to control mosquito populations which significantly limited the number of malaria and typhus cases in World War II; while the use of Atrazine has increased the production of corn and sugar cane farms and helped to supply the world
with the food it so drastically needs.
