CO High purity carbon monoxide is produced from lower purity material by a combination of purification techniques including molecular sieve and cryogenic fractional distillation.
Carbon Monoxide is a colorless, odorless, toxic, flammable gas. Shipped as a compressed gas. Carbon Monoxide Spec Sheet, 99.99% Carbon Monoxide Spec Sheet, 99.5% MSDS.
Impurity analyses of high-purity carbon monoxide gas using Mar 22, 2013 · We analyzed impurities in a high-purity carbon monoxide gas of semiconductor grade. A compact micro gas chromatograph was used for the impurity analyses. High-accuracy calibration gas mixtures by gravimetric blending method were used. The concentration of helium was found to be much higher than the other impurities. The purity of the high-purity gas was around 99.996% based on our
High-purity carbon monoxide (CO) gas as a certified reference material (CRM) was analyzed using a micro gas chromatograph (micro-GC) with a micro thermal conductivity detector. The main reason to select the micro-GC was its compact size to provide a safe experimental environment. Thus, both the CO gas cylinder and the micro-GC were placed inside a draft shield with a limited small space.
