What is the primary function of a TOC analyser?

A TOC analyser measures the total organic carbon content in water samples, indicating the level of organic contamination. This is crucial for water quality control in various industries.

How does membrane conductometric detection work?

This method oxidises organic compounds to CO₂, which then dissolves in a pure water stream. The resulting change in conductivity, measured by a sensitive sensor, correlates to the TOC concentration.

Is this unit suitable for pharmaceutical applications?

Units of this model are typically designed to meet regulatory requirements for pharmaceutical water analysis, including PW/WFI and cleaning validation, supporting major pharmacopoeias.

What kind of maintenance is typically required?

This class of equipment is known for low preventive maintenance requirements, with stable calibration often lasting up to 12 months, reducing operational downtime.

Can this analyser measure conductivity as well?

Some configurations or optional enhancements for this type of analyser can include Stage 1 conductivity measurement, providing additional water quality data.
