From clean water to wastewater: Maintaining reliable TOC analysis across changing sample matrices

Drinking water, surface water and wastewater differ in organic load, inorganic carbon, particles and concentration. These changes challenge TOC workflows.

For environmental labs, reliable analysis means managing different matrices without unnecessary manual steps.

The challenge starts before measurement

High-temperature catalytic combustion supports TOC analysis, but results also depend on sample introduction, pretreatment and dilution. Wastewater may bring particles, high concentrations or complex matrices.

An analysis can be automated while the surrounding workflow remains manual.

Handling more challenging samples

Particles can interrupt sequences through blockages or carryover. IGNIVIUS Direct Injection Technology is designed to support particle handling and reduce these risks; appropriate sample preparation may still be needed.

Adapting NPOC pretreatment to the sample

NPOC requires inorganic carbon removal, and sparging time can vary by sample. Smart Sparging adapts pretreatment and supports parallel NPOC processing while another sample is analysed.

Managing changing concentration ranges

Inline dilution automates dilution for samples outside the analytical range, helping manage unpredictable concentrations and reducing manual preparation.

Consistency is also a workflow issue

Automation standardizes repetitive steps so analysts can focus on calibration, quality control, exceptions and interpretation. IGNIVIUS supports TC, TIC, TOC, NPOC, POC and DOC, with optional TNb.
