Here is some of the most popular content posted on LCGC International this week.

LCGC International sat down with Christopher “Chris” Reddy of Woods Hole Oceanographic Institution, whose research was the basis for a recently released documentary.

Scientists recently studied how different factors affect antisense oligonucleotides (ASOs) under hydrophilic interaction liquid chromatography (HILIC) conditions.

When it comes to water analysis, it can be challenging for labs to keep up with ever-changing testing regulations while also executing time-efficient, accurate, and risk-mitigating workflows. To ensure the safety of our water, there are a host of national and international regulators such as the US Environmental Protection Agency (EPA), World Health Organization (WHO), and the European Union (EU) that demand stringent testing methods for drinking water and wastewater. Those methods often call for fast implementation and lengthy processes, as well as high sensitivity and reliable instrumentation. This paper explains how your ICP-MS, ICP-OES, and LC-MS-MS workflows can be optimized for compliance with the latest requirements for water testing set by regulations like US EPA methods 200.8, 6010, 6020, and 537.1, along with ISO 17294-2. It will discuss the challenges faced by regulatory labs to meet requirements and present field-proven tips and tricks for simplified implementation and maximized uptime.

Using ultra-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS), China Pharmaceutical University scientists developed a new method for analyzing compounds found in wastewater.

Scientists from the China University of Sciences combined magnetic solid-phase extraction (MSPE) with gas chromatography–mass spectrometry (GC–MS) to analyze perfluoro carboxylic acids (PFCAs) in different water environments.
