Detecting and Quantifying Mycotoxins with LC-MS/MS

mycotoxinWith the availability of sensitive mass selective instruments, such as tandem mass spectrometers and high-resolution mass spectrometers, today’s food safety chemists have the ability to accurately analyze multiple classes of mytotoxins simultaneously with minimal sample preparation. Mycotoxins, which are low-molecular weight, chemically diverse toxins, are produced naturally by molds commonly found in grains and fruit and have been linked to a wide range of negative health effects.
