Application note: Beverage-grade carbon dioxide purity analysis
March 10th 2023Beverage 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).
Application note: Ethylene oxide continuous emissions monitoring by OE-FTIR
March 9th 2023Industrial 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.
