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.

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 ...

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 ...

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 ...

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

Bipolar ionization technology releases charged atoms that attach to and deactivate harmful substances like bacteria, mold, allergens, and viruses. It first arrived in the US in the 1970s as a tool ...

Here's what research has found about the positive affects of negative ions: what they can and can't do and what is likely the best way to make sure you get a good dose if you want them.

The study, published in Building and Environment, mimicked real-world operating conditions for these ionization devices to test the effectiveness and potential to form chemical byproducts. (credit ...
