Scientists have made the first documented airborne detection of a toxic chemical pollutant known as Medium Chain Chlorinated Paraffins (MCCPs) in the Western Hemisphere. The findings, published in ACS ...

Explore how to boost confidence in your chemical ionization mass spectrometry results and see why gas reference materials are essential for reliable data in PTR-MS and SIFT-MS.

Medium-chain chlorinated paraffins, or MCCPs, have been detected in the air of Asia and Antarctica, but this surprise ...

In ACS’ Analytical Chemistry, researchers demonstrate a pen-like tool that can quickly and non-invasively collect molecules ...

LECO Corporation has announced a chemical ionization (HR-CI) source for the Pegasus GC-HRT (high resolution time-of-flight mass spectrometer). This field upgradable option empowers users to ...

Advion, Inc., a leading systems and consumables developer for the life sciences industry, announced today the launch of the novel volatile atmospheric chemical ionization source (vAPCI) for gas ...

Chemical ionization delivers less energy to the analytes and as a result causes less molecular fragmentation. During the analytical run, a reagent gas (usually ammonia, methane, or isobutene) is ...

Extractive electrospray ionization mass spectrometry (EESI-MS) allows the real-time, direct analysis of complex gaseous and liquid samples without any sample pretreatment under ambient conditions.

The researchers employed chemical ionization mass spectrometry to analyze trace gases in the air outside their lab between February and March 2016.
