Hi all,

we are about to recieve an older LCMS system, but I do not have the Site requirements plan

does anybody now the purity, flow and so on for the gas neede for this system?

I guess you only need nitrogen: then a good nitrogen generator with an hydrocarbon filter should be OK. The consumption of nitrogen should be maximum 600 l/hr and a minimum pressure of 7 bar must be guaranteed at such flow. Always put a pressure regulator before the nitrogen inlet so that the pressure does stays stable to 7 bar
