Hydrogen gas is increasingly being recognized as an ideal alternative to helium as a carrier gas in gas chromatography due to its cost-effectiveness and ability to maintain chromatographic resolution. However, the flammable nature of hydrogen necessitates strict safety measures during its use. F-DGSi's COSMOS hydrogen generators address these safety concerns by providing on-demand hydrogen production with controlled flow rates and pressures, thus reducing risks associated with high-pressure cylinders. The generators incorporate features like internal and external leak checks, automatic shut-off functions, and hydrogen sensors to ensure optimal safety. Positioning the generator close to the gas chromatograph further enhances safety by eliminating the need for long gas lines. In addition to safety benefits, these hydrogen generators offer high levels of purity, with up to 99.99999% purity achievable. They operate by electrolyzing deionized water using a titanium Proton Exchange Membrane cell, resulting in a high-quality hydrogen supply. The generators have a modular design, enabling customization based on lab requirements and saving bench space. By combining them with nitrogen or zero air generators, labs can streamline their gas supply for chromatography workflows. Moreover, the COSMOS hydrogen generators are designed for ease of use, featuring a touchscreen display for system status and auto-diagnostics, as well as LED indicators for straightforward operation. Remote monitoring and control via USB and internet connectivity further enhance convenience. These generators offer a reliable, safe, and sustainable solution for laboratories seeking to optimize safety and efficiency in gas chromatography applications, making them a preferred choice over traditional gas cylinders.
