Moisture measurement technology of a tunable diode laser absorption spectroscopy (TDLAS) analyzer is governed by Beer's Law. Therefore, by measuring the intensity of the laser before and after absorption, the number of moisture molecules in the sample can be determined because all other terms in the equation are constant. Because the laser is fine tuned to a moisture peak, a sensitivity (lowest detectable change) of 100 parts per trillion and a resolution of 200 parts per trillion are achieved. The high accuracy of this analyzer is proven by the 0.998 correlation with an APIMS.
