I know just about nothing about NPD other than what I have read; I have no firsthand experience, and as a result, have no idea what parts I need to upgrade this box to an NPD. Anyone happen to have a parts list that I will need, please?
Similarly, I would like to get away with nothing but hydrogen and air. The list of gases for this method occasionally lists as many as four, including helium and nitrogen. Is it possible to rig a 6890 N with nothing more than high-purity hydrogen and high-purity air and get good baselines and detection?
