Hydrogen is the perfect molecule for gas chromatography, especially for the replacement of the expensive Helium.

Peptide analysis in the GI tract shows links to endocrine, cardiac, and nervous systems. See how Hamilton Company isolates GPCR binding peptides with its PRP-3 column.

To address the Helium shortage GC laboratories have begun looking at possible replacement gases and new approaches to help obtain the carrier gases needed to continue their work. One of the most promising options is using the use of gas generators to provide a steady supply of hydrogen gas as a replacement for helium. Although some concerns—and some myths—persist about using hydrogen, it offers multiple benefits and advantages over helium, notably particularly when a gas generator replaces high-pressure gas cylinders.

Helium is running out, the worldwide demand is exceeding current production levels. Learn how Hydrogen could be your perfect replacement for Helium.

Beverage producers need to ensure the purity of carbon dioxide (CO₂) gas used to manufacture their products for consistent quality. They need a system that can both determine absolute purity and identify trace impurities at low levels. Industry-standard UV fluorescence analyzers are prone to maintenance issues causing extended downtime. This note demonstrates how a fully integrated solution – the Thermo Scientific™ MAX-Bev™ CO₂ Purity Monitoring System – provides the robust, reliable solution that beverage producers need. The system is engineered for demanding process environments and allows users to measure absolute purity along with trace impurities in CO₂ down to single-digit parts-per-billion (ppb).

Smart ramped pyrolysis-GC–MS analysis of forensic samples such as paint, adhesive tape, and mascara gives maximum info in a single run without method development.

Industrial facilities such as commercial sterilizers and chemical manufacturers frequently use ethylene oxide (EtO) in their processes. Due to the toxic nature of EtO, such users need to monitor for very low levels in and around their facilities. That can be particularly challenging with EtO which can present difficulties due to interfering species, high reactivity, a low boiling point, and other challenges. In this note, we examine how a familiar analytical technology is optimized for real-time, direct measurement of EtO. The Thermo Scientific™ EMS-10 System utilizes optically enhanced FTIR (OE-FTIR) technology to successfully address the many challenges of analyzing EtO quickly and with the required sensitivity.
