BTU 8000 Gas Chromatograph Stream Pressure Testing Technical Bulletin

This technical bulletin describes a procedure to test and balance sample stream pressures on a BTU 8000 gas chromatograph to improve repeatability and consistency of un-normalized totals. It instructs users to place the GC in hold mode, then check digital outputs for each stream while observing sample pressure, which should be around 9 to 12 psig when flowing.
