System Overview
The Sievers InnovOx On-Line TOC Analyzer consists of eleven major modules:
1.
Multistream module, which accommodates two or five sample streams, depending on the Analyzer
configuration. It also includes a vial port, which is used to calibrate the Analyzer. The multistream
module also includes a port through which a check standard can be measured.
2.
The sample pump accessory can be used to draw sample water to the multistream module from
sources that are not pressurized.
3.
Sample handling module, which draws sample into the Analyzer and mixes the sample with acid,
oxidizer, and dilution water. When NPOC is measured, the sample is sparged in this module.
4.
Gas control module, which controls the flow rates of carrier and sparge gas.
5.
The Air Purifier Accessory removes CO
the Analyzer can produce carrier and sparge gas from dry, oil-free compressed air.
6.
Reactor module where organics are oxidized to CO
• Reactor tube
• Heater and cooling fan
• Peristaltic pump
• Valves
7.
Gas-liquid separator, where carrier gas, containing CO
entering the non-dispersive infrared (NDIR) detector.
8.
NDIR module, containing an aerosol filter and the NDIR detector.
1.
All reagent usage estimates are based on default settings of 1% acid and 15% oxidizer.
