Thermo Fisher Scientific
Food and beverage manufacturers who perform simple sugar analysis require methods that provide sensitive, selective, and direct determination of carbohydrates. Minimizing errors associated with sample preparation is of key importance, because samples often require large dilutions that can impact the downstream accuracy of results. In this webcast, the benefits of using high-performance anion-exchange chromatography coupled with pulsed amperometric detection (HPAE-PAD), which does not require sample derivatization, will be discussed. We will also cover recent technological advances, including high pressure ion chromatography, which have enabled manufacturers to analyze more samples in less time.
Dr. Jeffrey Rohrer Director of Applications Development Thermo Fisher Scientific
Dr. Jeffrey Rohrer is Director of Applications Development for Thermo Scientific Dionex Ion Chromatography Products at Thermo Fisher Scientific. In this role, he directs the work of the corporate applications laboratory in Sunnyvale California. He also advises and reviews the work of other chromatography labs at Thermo Fisher Scientific. These labs develop HPLC, IC, HPAE-PAD, and other LC-based assays. Dr. Rohrer is an author of more than 70 peer-reviewed publications and is a member of the United States Pharmacopeia (USP) Expert Committee on Monograph Development for Chemical Medicines (Group 1), a member of the USP Expert Panel on Modernization of Identification Tests, and a member of the USP Expert Panel on Glycoprotein and Glycan Analysis. He is also the co-editor of a book titled Application of Ion Chromatography for Pharmaceutical and Biological Products, which was published in 2012. Dr. Rohrer joined Thermo Fisher Scientific (then Dionex) in 1989 and has held positions that include, Marketing Field Chemist, Senior Biochemist in R&D, and Applications Lab Manager. Prior to joining Dionex, he spent two years as a post-doctoral associate in Dr. Elizabeth Theil's lab at North Carolina State University studying the mechanism of iron deposition into the protein ferritin. Dr. Rohrer received his undergraduate degree in Chemistry from Franklin and Marshall College in 1981 and his Ph.D. in Chemistry from the University of Delaware working in the laboratory of Dr. Harold White III, studying the role of glycosylation in the transport of chicken serum riboflavin-binding protein across the oocyte membrane.
