Reliable water analysis starts with the whole workflow

Environmental and energy laboratories rarely work with one kind of water. Their samples range from drinking water, surface water and groundwater to wastewater, cooling water, condensate and process streams. Producing dependable results across these varied matrices takes more than a sensitive detector: sample introduction, pretreatment, throughput and gas supply all play a part.

IGNIVIUS, developed by Skalar and TRACE, brings decades of combustion-based TOC expertise into a system designed for today’s laboratories. High-temperature catalytic combustion and NDIR detection measure carbon, with optional chemiluminescence detection for total nitrogen. The analyser supports TC, TIC, TOC, NPOC, POC and DOC measurements.

The way a sample enters the analyser matters. IGNIVIUS Direct Injection Technology transfers it into the combustion zone through a short flow path. This supports low-volume and particle-bearing samples, including particles up to 800 μm, while helping reduce clogging and carryover.

NPOC analysis brings another challenge: samples do not all need the same pretreatment. Smart Sparging checks for residual inorganic carbon after pretreatment and adjusts sparging time when needed. This sample-responsive approach helps produce reproducible NPOC results and documents pretreatment effectiveness.

The workflow is designed to keep work moving. While one sample is measured, the next can be acidified and sparged, increasing throughput by up to 50%. Integrated inline dilution handles over-range samples and prepares working standards without dedicated dilution positions. The autosampler accommodates up to 170 (8 ml) vials for extended unattended runs.

Gas supply can also be part of the setup. IGNIVIUS is available with a ZA TOTAL C Zero Air generator, from LNI, a Velaris brand, which uses an integrated oil-free compressor and multi-stage purification to remove hydrocarbons, moisture, CO₂, CO, NO_x and SO₂ from ambient air. With flow capacities to suit different configurations, it offers point-of-use gas production and can reduce cylinder handling.

By bringing sample handling, responsive pretreatment, parallel preparation and optional Zero Air generation together, IGNIVIUS addresses the practical steps that shape everyday TOC and TN analysis.
