Figure Lengend Snippet: Schematic of NIST Dynamic Column Breakthrough Apparatus. Valve orientations and gas flow paths (red for sample and blue for purge) correspond to those at initiation of a sorbent column adsorption experiment (i.e. t0). Bold letters identify two-way, four-port rotary valves, and crossed circles are on-off valves with some labeled for reference in the text. MFC and MFM are mass flow controllers and meters, respectively. MS is the mass spectrometer, P1 and P2 indicate manometers of the total system pressure, and BPR refers to the backpressure regulators.
