Abstract
For determining concentration of a targeted molecule M in a liquid sample admixed with interfering molecules Mwhich overlap its absorption band, a NDIR reflection sampling technique is used. Besides the signal source, a reference and an interference source are added. M is calculated by electronics which use R(t) from a pulsed signal and reference channel output and a calibration curve which is validated by use of R(t) from a pulsed interference and reference channel output. Signal, interference and reference sources are pulsed at a frequency which is sufficiently fast so that a given molecule of M or Mwill not pass in and out of the liquid sampling matrix within the pulsing frequency.
