label: non-dispersive infrared cross-flow detector (en)

description: Instrument that uses a broadband lamp source and an optical filter to select a narrow band spectral region that overlaps with the absorption region of the analyte. The concentration of the analyte is determined from the intensity loss of the light in the narrow band region in presence of the analyte. Fixed amounts of sample and reference gas are injected alternatively in the measurement cell. (en)
