CAI PAS analyzers use photoacoustic infrared technology to measure many of the most commonly measured IR-absorbing gases. Gas selectivity is achieved through the use of optical filters that provide both a means of detecting the gas of interest and compensating for interfering gases and water. Both bench-top and rack-mounted PAS configurations are available.
An optional carousel is available to accommodate up to five additional gases. Typical applications for CAI PAS analyzers include:
