C-Sys: TOCII functions as a high temperature TOC
analyser without the need for fine or ultra filtration. Applications
include Municipal wastewaters containing significant solids levels,
industrial wastewaters with high salt concentrations, and relatively
clean river waters and cooling waters.

| C-Sys:
TOCII analyses aqueous samples for total organic carbon
using the catalytic thermal oxidation technique. Samples are delivered
to the analyser via a “fast loop” cross flow filter
and subsequently by peristaltic pump into the TIC stripping vessel
where acid is added and the mixture air purged to remove inorganic
carbon.
A pH probe controls
the addition of acid. The conditioned sample is then transferred
through a rotation slit filter, separating particles according to
DIN standards, and injected into the furnace either on a continuous
or a batch basis, together with CO2 stripped air to provide the
oxygen for reaction. Exhaust gases are cooled and cleaned to remove
aggressive acid gases, before going into a non dispersive infra
red detector where the level of CO2 is measured. The TOC is calculated
either from the sample flow/air flow/CO2 conc., or the total integrated
CO2 production over a batch, depending on which mode has been chosen.
