Product Overview
The WQA-4100 Water Quality (Total Nitrogen) Automatic Analyzer adopts high-temperature catalytic combustion technology and a chemiluminescence detector, with a syringe pump, multi-port switching valve, high-temperature combustion furnace, gas purification device, and NO gas conversion measurement module as core components. It converts nitrogen-containing compounds in the sample into nitric oxide gas for measurement, thereby calculating the total nitrogen content in the sample.
Product Features
- Adopts high-temperature sealed combustion-catalytic oxidation technology, with high total nitrogen conversion efficiency, and detects total nitrogen by chemiluminescence method.
- Adopts high-temperature sealed catalytic combustion technology, directly converting the liquid phase to the gas phase for measurement, unaffected by sample color and turbidity, with strong anti-interference capability.
- Adopts high-precision sample liquid quantification technology with syringe pump + rotary valve, featuring high metering precision and fast analysis speed, with a single measurement completed within 30 min. It also supports large-ratio automatic dilution, offering strong range expandability.
- Adopts chemiluminescence detection technology with high sensitivity, fast response, good selectivity, and low detection limit.
- High-precision PMT temperature control technology, with minimal drift.
- The TN measurement process requires no chemical reagents, and a built-in ozone purification device results in minimal secondary environmental pollution.
Application Fields
Suitable for surface water, centralized drinking water, domestic wastewater, and other fields.
