The new NDIR detector developed for the Sievers InnovOx TOC Analyzer achieves unprecedented TOC recoveries, regardless of sample matrix.

Non-Dispersive Infra Red (NDIR)

NDIR detectors measure CO2 in the gas phase. Most NDIR detectors are less stable than the two conductometric types and require frequent—in some cases daily—calibration.

However, GE Analytical Instruments' has developed a new NDIR reactor module that redefines robustness and achieves unprecedented TOC stability, regardless of sample matrix. This NDIR is used in the Sievers InnovOx Laboratory TOC Analyzer, which uses a unique Supercritical Water Oxidation (SCWO) technique. Unlike other TOC Analyzers with NDIR detectors, the Sievers InnovOx offers 6-month calibration stability and minimal maintenance.
