Bryan Troxell and other StrideBio scientists used size-exclusion chromatography with UV and multiangle light scattering (SEC-MALS) to measure changes in different viruses.

To quantify cyanide in different samples, a group of Brazilian scientists created a detection method based around headspace single-drop microextraction (HS-SDME).

Scientists from Essen, Germany recently created a method for simultaneously analyzing fatty acids (FAs) and fatty acid methyl esters (FAMEs).

A recent study published in the Journal of Separation Science reveals how ultrahigh-performance liquid chromatography tandem mass spectrometry (UHPLC–MS/MS) could be used to detect and quantify purine metabolites.

This article provides a high-level overview of Current Good Manufacturing Practice (cGMP) regulations and related public quality standards.

Scientists from South Dakota State University and the University of Colorado School of Medicine created a system to detect traces of cyanide in blood samples using liquid chromatography–tandem mass spectrometry (LC–MS/MS).

Scientists recently used laser desorption ionization mass spectrometry (LDI-MS) to detect toxic alkaloids in traditional Chinese medicines (TCM).

A group of scientists recently analyzed the metabolomics of individual cells using a pneumatically assisted (PA) nanospray desorption electrospray ionization (nano-DESI) probe of their own creation.

Two scientists from Baskent University in Ankara, Turkey analyzed multiple proteins in cream formulation using reverse-phase high-performance liquid chromatography.

Scientists from Qilu University of Technology in Jinan, China recently separated and purified components within the Phellodendron chinense plant using different types of counter-current chromatography (CCC).

In this LCGC Blog, Muhammad Farooq shares some tips for entering different careers within the analytical chemistry industry.

A group of scientists from the Luxembourg Institute of Science and Technology (LIST) tested different methods of using matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MSI) to analyze human skin cells.

Scientists from Egypt have developed a green reversed-phase high-performance liquid chromatography (RP-HPLC) method to determine the amounts of methionine and paracetamol in different mixtures.

To combat fraudulent sales of low-aged ginseng disguised as high-aged ginseng, scientists from Shanghai University of Traditional Chinese Medicine created machine learning models to predict the ages of ginseng samples.

To better understand the purity of therapeutic peptides, scientists from Germany, studied the effects supercritical fluid chromatography (SFC) could have during the analysis.

A team of scientists from Taizhou, China have developed a means of studying the medical effects of Qiangxin Lishui Prescription (QLP).

The methodologies demonstrated here open the way to fully compliant at-line monitoring of monoclonal antibody quality attributes.

The AES Mid-Career Award recognizes exceptional contributions to the field of electrophoresis, microfluidics, and related areas by an individual who is currently in the middle of their career. This year’s recipient, Robbyn K. Anand, Suresh Faculty Fellow and Carlyle G. Caldwell Endowed Chair in Chemistry at Iowa State University, has, along with her group, developed methods for circulating tumor cell analysis, electrokinetic enrichment and separation of chemical species within water-in-oil droplets, and more sensitive bioanalysis at arrays of wireless bipolar electrodes (1).
