Pesticide detection using deconvolution software

Share this on social media:

A team of analysts from the Chemistry Department at Tufts University, Gerstel GmbH, and Irish distillers Pernod Ricard utilised Ion Signature Technologies’ Quantitative Deconvolution Software to untangle complex spectra and determine the concentration of trace levels of compounds in considerably less time than that required for conventional data acquisition.

In one application, the time required to separate a lemon oil sample and determine the concentration of a series of pesticides, internal standards, and surrogates was reduced by approximately 75 per cent. The mass spectrometry software extracts each compound’s characteristic signature and untangles it from the surrounding matrix, delivering an ‘ion fingerprint’.
