Description
Gas preparation unit BPG-5M
The BPG-5M gas preparation unit is designed for preliminary preparation (filtration, drying, stabilization of operating parameters) of gases before they are supplied mainly to devices for flame spectral analysis and other devices that require purification of working gases.
The main area of application is the preparation of gases for flame atomic absorption spectrometers, including KVANT-2m , KVANT-2AT , KVANT -2A , KVANT.Z , KVANT.Z1 , mercury-hydride generators (GRG) and other analytical equipment.
The unit is designed for the preparation of the following gases:
propane,
acetylene,
nitrous oxide,
argon,
compressed air.
