摘要：

Calibration of moisture in HCl in the sub-ppm range was performed by gas-phase FTIR spectroscopy, giving a linear correlation between infrared absorbance and the moisture concentration. Minimum detectability was estimated to be 30 ppb with 5-min scan time at 2 cm-1 spectral resolution at 1.6 kg CM-2 pressure, using an InSb detector and an 8-m-pathlength gas cell.
