Optical Path Length Calibration: A Standard Approach for Use in Absorption Cell-Based IR-Spectrometric Gas Analysis

Figure 5

CO2 line profile in the 20 cm reference cell at 185 × 102 Pa (a) and the multipass gas cell (nominal length 21 m) at 6 × 102 Pa (b). The optical path length of the multipass cell was to be calibrated.
