B1 — NDIR Detector (for CO
2
Detection)
The Analyzer uses catalyst-free, high temperature combustion oxidation and Non-
Dispersive Infrared (NDIR) (B1) detection to measure a wide range of CO
2
, carbon
concentrations in complex sample matrices, including those containing high
concentrations of Total Dissolved Solids (TDS) and particulates. During the signal
integration phase, the NDIR signal rises as the measuring peak occurs and then
decreases as CO
2
is carried out of the NDIR Detector.
The NDIR Detector Analytical Range is specific to the hardware installed. This is
determined during product planning and custom installed individually per Customer
requirements. If there is a change in the sample location, the installed NDIR Detector can
be changed in the field. For more information, please contact Sievers Technical Support
or your Local Service Provider.
The "raw" NDIR Detector signals are displayed as “CO
2
in ppm” and the concentrations
are displayed in “mg/L”.
