Support for a Wide Range of Samples

The most important demand for on-line TOC analyzers is stable operation.
The TOC-4200 incorporates Shimadzu’s accumulated technical expertise to provide stable operation
across all scenarios from pure water to heavily polluted water.

˙ Range of sampling units to match a sample’s characteristics Flow Line Diagrams

• Sampling units are available for applications from pure water to heavily polluted water.
• Reduces instrument maintenance frequency.
TC NPOC
• Switch between measurement points for up to six flow lines. More economical since the need for multiple

˙ Measurement ranges from 5 mgC/L full-scale to 20,000 mgC/L full-scale
An option can be attached to support high sensitivity measurements to 1 mgC/L full-scale. TC NPOC (Note 2)
Acid Standard Recording section
• TOC measurement by acidify and sparge TOC also know as non-purgeable organic carbon (NPOC) NPOC solution Recorder or printer

˙ TN measurement option
Adding the TN measurement option permits total nitrogen (TN) measurements
(catalytic thermal decomposition – chemiluminescence detection). TN
Permits measurements from 1 mgN/L full-scale to 10,000 mgN/L full-scale.

Note 1) For the sampling section, select the multi-stream suspended solids sampling unit, the single stream suspended solids sampling unit, the
backwash strainer sampling unit or the sample stream kit (option).
Note 2) For the recording section, select either the recorder or the printer (options).
