The use of ultra high pressure liquid chromatography coupled with high resolution mass spectrometry (UHPLC-HRMS) is a relatively new hyphenated instrumental technique being considered in many food safety laboratories throughout the world. The advances in HRMS bench top instruments over the past decade have made this technology attractive to many laboratories looking to perform very broad pesticide residue screens. This talk will explore the practical use of this technology for routine and non-routine pesticide residue analysis in various food products. A focus on the practical advantages and disadvantages of HRMS over traditional tandem mass analysis for pesticide residue analysis will be covered, as well as, the challenges related to validation of methods and data handling.
