Yang C, Wang L, Ghosh D, Beck J, Humphries J. ASMS 2012 Poster The demand for quick and simple analysis of large numbers of samples in agriculture analysis is growing year by year. Throughout the world pesticides are used to control pests that are harmful to crops, humans and animals. These substances can pose a significant health threat and therefore, need to be accurately detected at the lowest levels requested by the governmental authorities typically at low part per billion (ppb) or low part per trillion (ppt) levels. Traditionally, triple stage quadrupole mass spectrometers have been used by the food industry to identify and quantitate these residues. The Thermo Scientific Exactive Plus Orbitrap mass spectrometer provides high-resolution, accurate mass (HR/AM) to unequivocally identify compounds without time-consuming analysis. The results of this unique solution are improved sensitivity and precision. Mass spectrometric detection for screening experiments with HR/AM technology using full scan experiments can detect as many analytes as necessary using only one chromatographic run. An Exactive™ Plus mass spectrometer with the proven power of the Thermo Scientific Orbitrap mass analyzer and Thermo Scientific TraceFinder software for unified quantitative and targeted screening data processing fulfills these demands with higher confidence and precision.
