The Sievers Membrane Conductometric Detection method for measuring total organic carbon (TOC) provides unmatched sensitivity, selectivity, stability, accuracy and precision.

Membrane Conductometric TOC

The Sievers Membrane Conductometric Detection method has proven to be an extremely reliable technique for measuring total organic carbon (TOC). Unlike instruments using NDIR (non-dispersive infrared) detection, the conductometric detection method exhibits an extremely stable calibration and is not susceptible to significant drift over time. This allows for less frequent calibration with no compromise in analytical performance.

The stability and reliability of the conductometric measurement is further enhanced by the Sievers membrane technology which utilizes a gas-permeable membrane that selectively passes only the CO2 produced from the oxidation of organics. By preventing compounds such as acids, bases, and halogenated compounds from interfering with the measurement of CO2 from oxidation, the Membrane Conductometric Method delivers unmatched sensitivity, selectivity, stability, accuracy, and precision.
