The Sievers M500e TOC Analyzer is available in two primary configurations: with the
standard iOS, offering one vial port and online monitoring; and with the Sample Inlet
Block, offering online monitoring only.
Discrete samples can be measured by the Sievers M500e TOC Analyzer by inserting a
filled 40 mL sample vial into the iOS System. Continuous monitoring is accomplished by
plumbing a sample line to the inlet of the iOS System or the Sample Inlet Block. The
stream splitter divides the sample stream into two equal but separate flows. One stream
is processed for the measurement of IC. The other is processed for TC measurement.
The TC stream passes to an oxidation reactor where the sample is exposed to UV light,
which oxidizes the organic compounds in the sample, converting them to CO
2
. The
reactor is a spiral quartz tube wrapped around the UV lamp.
