Environmental Analysis

In this LCGC blog, we reflect on the movement to make analytical chemistry more environmentally friendly, and how to potentially better those efforts for the industry's future.

By performing tissue analysis of caracals in captivity and in their natural African habitats, scientists were able to quantify uptake of toxic chemicals from the environment depending on how polluted they are.

The 20th International GC×GC Symposium will take place from 28 May–1 June 2023, and will be held in Canmore, Alberta.

A novel LC–MS/MS method, with a dual ESI and APCI source using simple solvent extraction for sample preparation, was validated for analysis of 102 pesticides and 5 mycotoxins regulated by Colorado state in dried hemp.

This month we interview Anele Mpupa from the University of Johannesburg in South Africa, about his work in sample preparation using liquid chromatography with mass spectrometry (MS), and his particular focus on water quality monitoring.

Analysis of unidentified organofluorine compounds and known PFAS in environmental and human samples presents many challenges. Combustion ion chromatography is one technique that can help.

How to speed up sample prep time and equivalent acccuracy and precision.

How to lower the limits of quantitation as the regulatory landscape continues to evolve.

Exploring the concerns surrounding the use of organotin compounds and their impact on the environment and potential toxicity to mammals.

The Column spoke to Brett Paull from the University of Tasmania in Hobart, Australia, about the development of truly portable LC systems for use in the pharmaceutical industry and in environmental analysis. Why are they necessary, and where can improvements still be made?

Are generic workflows really needed in environmental analysis? In the end, it is the analyst— not instrumentation or software—that is in charge of what data are obtained, after thoughtfully considering what sample preparation and acquisition method to use.

The Column spoke to Philipp Weller from the Institute of Instrumental Analytics and Bioanalytics at the Mannheim University of Applied Sciences, Germany, about the benefits of nontargeted screening approaches in food safety and environmental analysis using GC–IMS, and the best way to approach data processing and model building with the generated data.

A TD–GC×GC–TOF-MS method for malodour detection

Newer direct-injection mass spectrometry techniques can improve real-time monitoring of volatile organic compounds.

How to successfully identify and measure PFAS and adapt to the evolving regulatory requirements for a wide variety of sample matrices using LC–MS/MS

Perfluorinated carbonic and sulfonic acids were determined by SPE–LC–MS/MS

Sample preparation primarily for water samples in PFAS.

The Column spoke to Stefan Van Leeuwen and Bjorn Berendsen about a novel nontargeted approach to analyze PFASs using LC–HRMS with FIF.

Microextraction techniques have evolved since their appearance three decades ago, moving toward the use of greener and sustainable materials and solvents.

An improved LC–MS/MS method that can rapidly detect fipronil, an insecticide harmful to human health, is presented here for chicken eggs, feed, and soil.
