BTU 8000/8100 Gas Chromatograph CO2 Manual Gating Technical Bulletin

This technical bulletin describes a procedure for improving the performance of the BTU 8000/8100 gas chromatograph when analyzing gas samples with very low concentrations of CO2. It explains how to use the xxGT command to manually set gate on and off times for CO2, bypassing the auto-gate method to achieve lower detection limits, provided baseline noise issues are resolved first.
