LAR Process Analysers

Advanced TOC and Wastewater Monitoring Solutions

When you need reliable insight into water pollution levels, LAR Process Analysers provides robust online analyzers designed for industrial wastewater, process control, and environmental monitoring.

By measuring key sum parameters such as TOC and COD, LAR systems give you continuous, actionable information about the total pollution load – even in complex and variable water streams.

Measuring Total Pollution Load for Better Process Control

LAR Process Analysers AG is a German manufacturer headquartered in Berlin and founded in 1986. The company develops online analyzers for industrial processes, wastewater treatment, and environmental monitoring, with a focus on measuring overall water quality rather than individual compounds.

The systems are based on the concept of sum parameters – measurements that describe the total pollution level in water:

TOC – Total Organic Carbon Measures total organic contamination in water
COD – Chemical Oxygen Demand Indicates the oxygen required to oxidize pollutants
BOD – Biological Oxygen Demand Reflects biodegradable organic load
TNb – Total Bound Nitrogen Supports nitrogen monitoring and eutrophication control
Toxicity monitoring Detects harmful substances that may disrupt biological treatment
Total Phosphorus (TP) Important for nutrient control and regulatory compliance

In practice, this approach gives you a consistent picture of water quality, even when the composition of your wastewater changes.

High-Temperature Combustion Ensures Complete Oxidation

Many LAR analyzers use a ceramic combustion furnace operating at approximately 1200 °C, where the entire sample is oxidized under controlled conditions.

At this temperature:

All organic compounds are converted into CO₂
The measured CO₂ directly represents the Total Organic Carbon (TOC)
Complex and difficult wastewater matrices can be handled reliably

This means you get true TOC values, without relying on correlations or indirect methods.

X-Y Injection System Enables Measurement of Unfiltered Wastewater

Several LAR analyzers use a unique X-Y sample injection system, designed to handle real wastewater conditions without the need for filtration.

The system moves the dosing unit in both horizontal and vertical directions, which allows:

Accurate and repeatable sample injection
Measurement of unfiltered samples with particles up to 0.8 mm
Reduced risk of clogging
Automatic rinsing of the injection needle between measurements

For you, this means stable operation even in particle-rich industrial wastewater, where traditional analyzers often require extensive sample preparation.

Biological Monitoring Protects Your Treatment Process

In addition to chemical parameters, LAR offers analyzers that monitor biological activity and toxicity in wastewater.

This allows you to:

Detect toxic substances before they affect your biological treatment
Monitor nitrification performance
Understand how microorganisms respond to changing conditions

In practice, this gives you an early warning of process disturbances, so you can act before they impact performance.

Supporting You Across Wastewater and Environmental Applications

Whether you operate a municipal plant or manage industrial discharge, you need reliable data to:

Monitor organic load at inlet and outlet
Detect toxic shocks from industrial processes
Optimize biological treatment performance
Ensure compliance with environmental regulations
Protect receiving waters and downstream processes

With continuous measurement, you are able to respond earlier and operate with greater stability.
