Total Organic Carbon Sensor
Top Performance and Easy Installation
Total organic carbon control is
essential in the production of high
purity pharmaceutical waters. For a
system fabricator involved in a major
water project, a METTLER TOLEDO TOC
sensor gave them the competitive edge
they needed to win the deal.
A Water for Injection project
Scandinavia is home to one of the
world's largest manufacturers of
diabetes treatments. Water for Injection (WFI) is critical at the company's
many production facilities, so ensuring
WFI is always in specification is vitally
important.
When the total organic carbon (TOC) sensors installed
at the company's main production plant were becoming obsolete due to lack of spare parts, a water system
fabricator worked with the client to propose three TOC
sensors, including one from METTLER TOLEDO, to determine which one would best meet their requirements.
A unique, continuous solution
Most TOC analyzers only measure periodically,
typically once every six minutes or more. The water
system fabricator recognized that for pharmaceutical
companies, who need to know the quality of their pure
waters at all times, such batch measurements mean
an increase in TOC followed by a return to previous
levels can be completely missed. METTLER TOLEDO

Thornton's range of on-line TOC sensors measure
continuously. Therefore, any change in TOC is identified immediately.
High measurement uptime
Water system fabricators know maximum sensor uptime
is critical for their clients. In the case of the METTLER
TOLEDO on-line TOC sensors, very little can go wrong
with them. Unlike other TOC sensors, METTLER TOLEDO's
TOC sensors have no pumps, membranes, heat
exchangers, or other elements likely to require regular
maintenance.
Further, predictive diagnostics continuously monitor
how well the sensor is operating. This enables proactive
