We understand the challenges faced by food laboratories - Food safety standards change and evolve, so what was once at the lower end of permissible pesticide residues analysis results today, may be at the upper end tomorrow. We provide powerful workflow solutions from sample matrix, through demanding chromatographic separation requirements and final analysis. Let us help improve the robustness of your workflow and boost your productivity with our portfolio of sample preparation, GC, and LC products designed to meet your expectations.
I am looking to switch my pesticide methods from GC-MS to LC-MS, what do you recommend?FSMA mandates a “science-based” approach to food testing. This does not require that Chromatography be used, but in practice, much of the modernization of food testing methods has been driven by the use of new and improved chromatographic . . . |
GC applications for fatty acids are run on either an FFAP phase or on a low polarity phase. Why is this?Short chain fatty acids can be separated on a Zebron ZB-FFAP column, which will provide a unique selectivity and good peak shape. . . |
What kind of analytes is roQ™ QuEChERS suitable for?QuEChERS was originally developed to simplify the analysis of pesticides in food matrices. It can be used for any analytes which partition into acetonitrile rather than water. In practice, this means any analytes with a log P value of greater than 1. |
Does FSMA Equal Chromatography?FSMA mandates a “science-based” approach to food testing. This does not require that Chromatography be used, but in practice, much of the modernization of food testing methods has been driven by the use of new and improved chromatographic... |
What is the Food Testing Method Modernization Movement?Chromatography - whether gas, liquid, or some other variation – is an analytical tool whose primary purpose is to separate one chemical species from another, i.e., to “speciate”... |
FSMA and Scientifically Valid MethodsAs mentioned in the previous post, FDA requires that food testing methods be scientifically valid. FDA starts with this deeply fundamental premise, but does not dictate a prescribed solution. This is in contrast to other regulatory agencies,... |
