Full-Scan Fragmentation Options for the Detection of Food Contaminants by an Affordable LC-Q-Orbitrap MS

Instrument Type: LCMS

The analysis of food toxicants is challenging because of the high number of substances that need to be analyzed. Pesticides alone account for over 800 analytes including other types of toxicants such as mycotoxins, plant toxins and/or veterinary drugs. The use of liquid chromatography with full-scan, high-resolution accurate mass spectrometry (HRAM) as an alternative is gaining in popularity. We compare two different scan options of a quadrupole-Orbitrap system, both offering full mass range fragmentation techniques, and to optimize performance in terms of sensitivity and selectivity
