FTIR-based moisture analyzers

The V Series FTIR-based analyzers, designed for measurement of trace H2O contamination in corrosive gases, can reach the lower detection limit of 10 ppb of H2O in matrices of HCl, HBr, and NF3. These results are attained in real time, with measurement intervals <1 min. The spectrometer compartment is evacuated (to 10-5 torr) to eliminate background atmospheric moisture, rather than the conventional approach of purging the instrument. This reduces setup times to 24 hours. MIDAC Corp., Irvine, CA; ph 714/660-8558, fax 714/660-9334, e-mail [email protected], www.midac.com.
