Please join the Chemistry Department for the final talk of the fall 2023 seminar series, “Towards In-Field Miniaturized Liquid Chromatography: Biocides in Wastewater as a Proof of Concept,” presented by Robert Ernst, M.S. in forensic science candidate at SUNY Buffalo State University, on Thursday, December 7, at 12:15 p.m. in Science and Mathematics Complex 175.

Abstract
Advancements in technology have led to a push for the portability of benchtop lab equipment. Many instruments have been miniaturized and made handheld such as the Raman spectrometer. With the increase in the portability of instruments, there is a decrease in the analysis time of samples. Crime-scene analysis time is quite long in some areas as the evidence is transported back to a central lab to be tested. The portability of certain instruments can help reduce the analysis time of evidence. Many models of miniaturized liquid chromatography have been created. The integral parts of liquid chromatography had to be miniaturized. A proof of concept was developed for the analysis of biocides in wastewater for a new portable LC. Authors compare two benchtop liquid chromatography instruments to a portable liquid chromatography instrument. The portable version uses less solvent than HPLC, and the portable instrument can comparably quantify the biocides to the benchtop instruments. The field conditions have little effect on the portable instrument’s ability to analyze compounds. The merits of portable liquid chromatography instruments versus the benchtop instruments are compared.
