Speciation Analysis of Volatile Arsenic Compounds in Gas and Liquefied Gas Samples using GC-ICP-MS

Agilent Technologies has produced an application note describing a novel gas sampling system that enables simultaneous GC-ICP-MS analysis of total and speciated volatile arsenic compounds such as arsine in gas and liquefied gas samples.

Per- and Polyfluoroalkyl Substances in Drinking Water Using Solid-Phase Extraction and LC-MS/MS

UCT has produced an application note outlining a simple solid-phase extraction procedure for the extraction of 26 diverse per- and polyfluoroalkyl substances (PFASs) in drinking water using UCT’s polymeric weak-anion exchange SPE cartridges...

Innovative Cryogen-free Ambient Air Monitoring of Trace-level Air Toxics at High Humidity

Markes International has produced an application note describing how a canister autosampler (using innovative cryogen-free water-removal technology) and thermal desorption–gas chromatography–mass spectrometry (TD–GC–MS) together allow the...

Improving resolution of PAHs

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous in the environment. They belong to a group known as persistent organic pollutants (POPs) and their monitoring is important because they have been identified as carcinogens. Multiple isomers...

Lowering costs in your environmental lab...

Environmental laboratories are always looking for ways to save costs without compromising analytical results in terms of sensitivity, robustness or quality controls.

Online monitoring of atmospheric aerosols

Atmospheric aerosols exert a large but uncertain negative (cooling) radiative forcing on regional climate. Their chemical composition affects this climate forcing via aerosol hydroscopicity and consequential cloud interactions, as well as...
