Abstract: The enormous growth in the craft brewing sector coupled with the popularity of IPA-style beers has led to an increased demand for Hops (Humulus lupulus). It is anticipated that the demand for routine pesticide monitoring will likewise continue to rise. Due to their matrix complexity, hops have traditionally been a difficult commodity to monitor for pesticide use. In addition to normal matrix interferences from strongly pigmented samples, the vast array of flavor and fragrance components within the samples are often orders of magnitude larger than pesticides you wish to monitor. In this study, gas chromatography was combined with time-of-flight mass spectrometry (TOFMS) to detect commonly monitored pesticides in whole leaf hops.Summary: The Pegasus BT’s exceptional sensitivity combined with ChromaTOF’s industry-leading deconvolution with Target Analyte Find allows for excellent quantification of pesticides in challenging matrices.
Time-of-flight data acquisition allows the user to collect and store a wide mass range without sacrificing sensitivity. Data can be reevaluated later for peak information not targeted in the initial analysis.
