Running a small or medium environmental lab often feels like a race against time and resources. Recent EPA actions against per- and polyfluoroalkyl substances (PFAS), such as designating PFOS and PFOA as hazardous substances in drinking water and enforcing strict limits under Methods 533 and 537.1, have added to the testing burden on labs. Maintaining meticulous sample prep becomes even more critical as the need for accurate, contamination-free results intensifies.
Nitrogen evaporators offer a streamlined, efficient solution to the challenges of solvent evaporation, one of the biggest time bottlenecks faced by labs. The use of inert nitrogen gas ensures a gentle evaporation process that preserves sample integrity, and precise temperature control enhances accuracy. These systems enable simultaneous processing of multiple samples, significantly reducing preparation time.
However, nitrogen evaporators require precise manufacturing and proper setup to function optimally. Effective integration and operation of these systems can enhance lab productivity while ensuring compliance with regulatory standards for drinking water and other sample types.
