The chromatography lab opened in 1976. The initial intent for the chromatography lab was to support our clients battling herbicide carry over. Since the lab's inception in 1976, the lab has become a central focus for continuous method development, expanding well beyond herbicide support.

Through our chromatography lab, Midwest Labs focuses on method development and analytical testing. We utilize 45 unique instruments for chromatographic analysis, including: HPLC, LC/MS/MS, GCFID/ECD, Headspace and GC/MS/MS to produce consistent and repeatable analysis for mycotoxins, antibiotics, pesticides, vitamins, and so much more. Combine the instrumentation with our phenomenal method development team, and you get new tests such as Pentobarbital and Thyroxine, expanding our customers' options for testing and safety.
