Find out more about Chromatography Research Supplies (CRS), now part of the Trajan family of brands.
A high-capacity gas purifying system that can remove a combination of oxygen, moisture and hydrocarbons (greater than C4) from inert gases and hydrogen.
GC and GC/MS carrier gas, ECD make up gas and ICP. The AFS purifiers can be expected to supply multiple installations for an extended period of time depending on the laboratory environment.
