Combustion Total Organic carbon TOC analyzer

1.The model ET1020A TOC analyzer is an automated system for the analyzing aqueous samples for total carbon (TC), total organix carbon (TIC), total organic carbon (TOC).

2.The fixed volume sample loop introduction system allows repeatable analysis over a wide range of concentrations.

Features:

2a. Designed for analyzing samples containing up to 10,000ppm C.

2b. Combustion temperatures

Carbon compounds combust in an oxygen-rich environment, resulting in complete conversion of carbon to carbon dioxide (CO₂). TC is determined when the NDIR detector detects the resulting CO₂ TIC is determined by measuring CO₂ released following sample acidification. As the sample pH lowers, carbonate and bicarbonate ions convert to dissolved CO₂, which is purged from solution and swept into an NDIR detector. The NDIR detector is calibrated to display the mass of CO₂ detected. TOC is determined by performing separate TC and TIC analyses and subtracting the results.

TOC = TC - TIC
