We will discuss the capabilities of a modern gas chromatograph-triple quadrupole mass spectrometer (GC-TQMS) to perform pesticide analysis of cannabis, fruits, and vegetables. As a starting point, we will give a brief overview of the instrument and its unique collision cell technology. We will then present the pesticide results of our cannabis experiments as well as data from some fruit and vegetable samples purchased at a local grocer.
Key Learning Objectives:
Dr. Jensen attended Colorado School of Mines starting in 2008 for graduate studies. During his time in graduate school, he studied mass spectrometry under Dr. Kent Voorhees at Colorado School of Mines. His dissertation work included analysis of NPAH’s in biofuel combustion, development of an LFI strip to detect Bacillus anthracis using bacteriophage amplification, and multivariate statistical analysis of MOLI mass spectral data of various bacteria for the purposes of identification. He received a PhD in Applied Chemistry from Colorado School of Mines in December, 2014.
He then took a position as a research scientist at Osaka University, and was promoted to assistant research professor after two years. He started at JEOL USA, Inc. as an applications chemist in 2019, and his current projects involve the JMS-TQ4000GC triple-quad mass spectrometer.
