CIC Photonics responded by first modifying its long path 10.0-meter Pathfinder gas cell for measurements of moisture in the acid gases (HCl, HBr, WF6) to a LOD range of 100 to 150 ppb with an appropriate FTIR spectrometer. Continuing its effort to meet demands, the company designed first its 4Runner 4.0-meter cell and then its Ranger 9.6-meter gas cell; both cells were designed to achieve the highest energy throughputs possible and rapid exchanges of gas samples from sample to sample. The high energy throughputs (40% to 60%) provided the additional advantage of the end user using a FTIR spectrometer with a DTGS detector, instead of LN2-MCTs in industrial applications.
Once the company created the IRGAS line of gas analyzers, it designed the Moisture+Plus as the IRGAS Solution for its electronic specialty gas customers. This analyzer was designed to eliminate all interfering external moisture sources from the optical paths of the FTIR’s infrared beam. To accomplish this goal, the physical configuration of the FTIR gas analyzer and gas cell were adjusted to permit high purity N2 purging of the spectrometer, gas cell, and all optical pathways. With the current configuration of the IRGAS Moisture+Plus and the IRGAS-SUPR, moisture LODs of 1 to 5 ppb are achievable.
