LCGC Magazine is pleased to announce the addition of David S. Bell to its editorial advisory board.
Over the past 20 years, Bell has worked directly in the chromatography industry, focusing his efforts on the design, development, and application of chromatographic stationary phases to advance liquid chromatography and related hyphenated techniques.
He is a research and development manager in the HPLC Surface Chemistry and Health Sciences Research department at Sigma-Aldrich/Supleco.
Bell’s main objectives have been to create and promote novel liquid chromatography (LC) technologies and to conduct research on molecular interactions that contribute to retention and selectivity in an array of chromatographic processes. His research results have been presented in numerous symposia worldwide, and have resulted in several peer-reviewed journal and trade magazine articles.
Bell’s undergraduate studies were done at the State University of New York at Plattsburgh (SUNY Plattsburgh). He received his PhD in analytical chemistry from The Pennsylvania State University (State College, Pennsylvania) and spent the first decade of his career in the pharmaceutical industry performing analytical method development and validation employing various forms of chromatography and electrophoresis.
Determining Volatile Impurities and Ethanol Content in Hand Sanitizers with GC–MS
September 10th 2024Researchers analyzed 31 different brands of hand sanitizers using headspace gas chromatography-mass spectrometry (GC–MS) to assess volatile impurities and ethanol content in ethanol-based hand sanitizers.
Modern HPLC Strategies: Improving Retention and Peak Shape for Basic Analytes
August 16th 2024In high-performance liquid chromatography (HPLC), it is common for bases and unreacted ionized silanols on silica-based columns to cause irreproducible retention, broad peaks, and peak tailing when working with basic analytes. David S. Bell, Lead Consultant at ASKkPrime LLC offers innovative HPLC strategies that can help mitigate such issues.
