Ndir Detector TOC

TOC Application Handbook -

an NDIR detector wet chemical oxidation, which applies a combination of UV irradiation and persulfate for oxidation. The resulting CO2 is either detected via an NDIR detector or using a conductivity detector. For TOC determination in wastewater, catalytic combustion has become the method of choice based on its higher oxidation

TYPES OF TOC DETECTORS - SHIMADZU CORPORATION

Total Organic Carbon (TOC), can be detected by using either the Non-Dispersive Infrared (NDIR) or the conductivity detector. The NDIR is more popular than the conductivity detector, due to stability and interference issues. NDIR detectors measure carbon, or more specifically CO2 in the gas phase, while conductivity detectors measure CO2 in the liquid or aqueous phase.

NDIR Sensor for Non-Dispersive Infrared Detection

This is a non-dispersive infrared (NDIR) approach. It has been shown (Jacquinot P. 1954 J. Opt. Soc. Amer. 44, 761-765) that optical filters are typically 1000 times more efficient than gratings and up to 100,000 times more efficient than prisms at separating IR wavelengths, so NDIR gas sensors offer real performance advantages over dispersive ...

QbD1200 Lab TOC Analyzer Frequently Asked Questions

sensors used to measure TIC and TC can be much larger than the TOC, so, when the TOC is calculated, the measurement errors can lead to an over-reporting of TOC or the reporting of a negative TOC value, in a water sample containing 1900ppb TIC and 2000ppb TC with a sensor accuracy of +/-2%: Measured TC = 1960ppb to 2040ppb
