With a new laboratory addition (7,200 ft2) and remodeling of the existing building, we now have an improved 19,200 ft2 facility to accommodate growth in Micro, GMO, Metals, Nutrition, and Pesticide residue testing. For the pesticide residue department, this includes eight new fume hoods, an additional freezer storage room (with back-up power supply), larger sample preparation space, a dedicated room for preparing analytical standards, rooms for new GC and LC instrumentation. Our most recent instrument purchase, a Sciex 6500 QTRAP LC/MS/MS, is certified for GLP work and has been used for 3 projects.During the last year we added 40 new analytes to our testing library, including metabolites and breakdown products, and completed the development and validation for 5 new testing methods, expanding the total number of chemicals we test to over a 1,000. Our popular 'extended' pesticide residue screen, which uses the QuEChERS method and gas and liquid triple quadrupole mass spectroscopy, includes 474 pesticides.
