In the Rising Stars of Separation Science interview feature, we speak with early-career researchers about their passion for chromatography, their current research focus, and their plans for the future.
This special article series highlights the work of young analytical chemists.
“LC Troubleshooting” makes HPLC easier to master, by explaining the fundamentals of liquid chromatography separations and offering troubleshoot advice. Dwight Stoll, a professor and the co-chair of chemistry at Gustavus Adolphus College in St. Peter, Minnesota, and a recognized leader in two-dimensional LC, took the helm at the “LC Troubleshooting” column following John Dolan‘s retirement in October 2017. In this archive, you’ll find the latest articles from Dwight as well as past installments from John through 2000. You can find older articles from John on the LC Troubleshooting Bible website.
"Column Watch” provides practical information about liquid and gas chromatography including updates on new methods and approaches, explanations of recent developments and technologies, and advice for improving your separations. Columnist David S. Bell is a director of Research and Development at Restek. Over the past 20 years, he has worked to create and promote novel separation technologies and to conduct research on molecular interactions that contribute to retention and selectivity in an array of chromatographic processes.
"GC Connections” keeps readers up to date on the latest in methods, techniques, technologies, and best practices for gas chromatography. Columnist Nicholas H. Snow is the founding endowed professor of the Department of Chemistry and Biochemistry at Seton Hall University. He is interested in the fundamentals and applications of separation science, especially gas chromatography, sampling, and sample preparation for chemical analysis. His research group is very active, with ongoing projects using GC, GC–MS, two-dimensional GC, and extraction methods including headspace, liquid–liquid extraction, and solid-phase microextraction.
“Sample Prep Perspectives” keeps you up to date on new developments in sample preparation and provides practical tips to improve the effectiveness and ease of your sample preparation processes. Columnist Douglas E. Raynie is a department head and associate research professor at South Dakota State University. His research interests include green chemistry, alternative solvents, sample preparation, high resolution chromatography, and bioprocessing in supercritical fluids.
"Perspectives in Modern HPLC” brings fresh scientific perspectives to chromatography practitioners, covering technical issues, innovative ideas to make chromatography less arduous, and explanations of less-familiar approaches. Columnist Michael W. Dong is a principal at MWD Consulting, where he provides training and consulting services in HPLC, UHPLC, pharmaceutical analysis, and drug quality. He was formerly a senior scientist at Genentech, a research fellow at Purdue Pharma, and senior staff scientist at Applied Biosystems/PerkinElmer.
“Focus on Biopharmaceutical Analysis” assesses new approaches as well as best practices in all aspects of the analysis and characterization of protein-based pharmaceuticals, such as monoclonal antibodies, antibody–drug conjugates, bispecific antibodies, and new modalities as they develop. Anurag Rathore is a professor in the Department of Chemical Engineering at the Indian Institute of Technology in Delhi, India. Jared Auclair is the Vice Provost Research Economic Development and Director of Bioinnovation at Northeastern University, in Boston, Massachusetts.
"Biopharmaceutical Perspectives” covers current cutting-edge methods and trends involving chromatography in the constantly evolving biopharmaceutical sector. Columnist Koen Sandra received a PhD degree in Biochemistry from the Ghent University, Belgium in 2005. After his PhD, he joined Pronota, a molecular diagnostics company where he was active in developing analytical platforms for disease biomarker discovery and in setting up external collaborations. In 2008, he joined RIC, a company that provides chromatographic, electrophoretic and mass spectrometric support to the chemical, life sciences and pharmaceutical industries, where he holds the position of CEO. As a non-academic scientist, Koen Sandra is author of over 50 highly cited scientific papers and has presented his work at numerous conferences as an invited speaker.
"Questions of Quality” offers guidance for scientists working in regulated laboratories, covering topics such as regulatory compliance, data integrity, chromatography data systems, and laboratory information management systems. Columnist Bob McDowall is an analytical chemist with more than 45 years of experience including 15 years working in the pharmaceutical industry and more than 25 years working for the industry as a consultant, helping laboratories in areas such as training staff in regulatory compliance, implementation of laboratory informatics, and qualification of IT infrastructure.
“The LCGC Blog” has two threads. In one, Tony Taylor, the chief scientific officer of Arch Sciences Group and the technical director of CHROMacademy, LCGC’s online learning partner, offers practical tips on separations. In the other, members of the American Chemical Society Analytical Division Subdivision on Chromatography and Separations Chemistry (ACS AD SCSC) share perspectives on a range of topics in separation science. This thread includes occasional installments from Kevin A. Schug of the University of Texas at Arlington, who began this blog thread solo in 2013.
"Incognito” provides a sometimes controversial viewpoint on developments, trends, and factors affecting those working in separation science.
"Focus on Environmental Analysis" covers environmental scientists providing updates on changes in regulations as well as advances in methods for detecting and quantifying environmental analytes in various matrices.
Invited experts share the latest methods and best practices for food and beverage analysis, on topics such as pesticide analysis, food safety, authentication of origin, and more.
