Secure Your Lab's GC Workflow with On-Demand Gas Generation
Sep 03 2024
Eliminate the inconvenience of gas cylinders and embrace reliable, high-purity gas supply for your GC and GC-MS with the COSMOS Gas Generators by F-DGSi. These generators deliver on-demand Hydrogen, Nitrogen, and Zero Air, streamlining your lab's workflows and boosting precision.
Modular Solution for On-Demand Hydrogen, Nitrogen and Zero Air
The F-DGSi COSMOS gas generators are tailored for GC and GC-MS applications. With their stackable and modular design, the generators offer your lab a customizable solution to produce Hydrogen, Nitrogen and/or Zero Air on demand. These gases are essential for carrier gas and makeup gas to sample preparation and manifold operations. You can choose from standard or high-purity models to meet the specific gas requirements of your GC and GC-MS instruments.
High Purity Hydrogen Gas Generator
F-DGSi’s COSMOS hydrogen generators provide a reliable and practical alternative to gas cylinders and helium as carrier gases. They produce Hydrogen by electrolysing deionized water using a 100% titanium Proton Exchange Membrane (PEM) cell, which ensures a longer generator life. The Hydrogen is then purified and dried through various methods, such as adsorption drying, desiccant cartridge drying, or Permapure drying, to meet the required purity for your applications.
The COSMOS generators deliver on-demand hydrogen at flow rates from 100 – 1500 cc/min with purities up to 99.99999%. Once installed, the generator ensures constant Hydrogen purity 24/7.
High Purity Nitrogen Gas Generator
The COSMOS N2 / ZN2 generators are designed to optimize the supply of high purity Nitrogen for various applications, including GC-make-up, GC carrier gas, headspace vial pressurization, purge and trap, and tube conditioning for thermal desorption. They use reliable pressure swing absorption (PSA) technique to remove Oxygen and moisture, producing high purity Nitrogen with a purity up to 99.9995%. A built-in catalyst also removes hydrocarbons to < 0.05 ppm.
Zero Air and Compressed Air Generator
The COSMOS Zero Air Total generators produce dry, hydrocarbon-free air from oil-free compressors, suitable for use as GC detector gas. Hydrocarbons and CO are removed by a catalytic oven filled with palladium. Humidity and CO2 are eliminated using a dual molecular sieve PSA system, while NO is removed with Purafil. Other components are filtered out with active charcoal.
The reduction of hydrocarbons, including Methane, and Carbon Monoxide lowers background noise and improves baseline stability, significantly increasing detector sensitivity and ensuring precise analytical results.
The COSMOS Air Compressor produces continuous, high quality oil-free, pre-dried air and is the ideal solution for providing compressed air to a Zero Air and Nitrogen Generator and for powering pneumatic valves or other applications in the lab.
Make your own COSMOS gas generator tower
The COSMOS gas generators are designed for safety and convenience, eliminating the need for high-pressure gas cylinders. Built with high-quality components, easy to install, with minimal annual maintenance. Their modular and stackable design saves space, allowing easy placement alongside GC or other applications for seamless integration into your laboratory environment. Just combine any module to generate the gas for your GC & GC-MS.
