What is the difference between a process analyzer and a laboratory analyzer?

The following table compares process analyzers to laboratory analyzers: Feature Process analyzer Laboratory analyzer Location Installed directly in the process Located in a separate lab Measurement frequency Continuous or at set intervals Periodic, depending on manual sampling Response time Real-time results Delayed results after transport and analysis Accuracy High, suitable for process control Very high, suitable for detailed analysis Safety Reduces manual handling of hazardous samples Requires operators to handle samples

Can I determine trace levels of cations and anions in ultra-pure water online?

Yes, you can measure trace levels (to % levels) of cations and anions in ultra-pure water online, for instance with the 2060 IC Process Analyser . The 2060 IC Process Analyser supports: Simultaneous analysis of multiple parameters (cations, anions, trace metals) Multiple detection methods: conductivity (suppressed and non-suppressed), UV/VIS, and amperometric detection Autonomous operation: 24/7 monitoring with continuous eluent generation Modular configuration: up to four cabinets and 20 sample streams can be integrated

What is a process analyzer?

A process analyser is an instrument that measures the chemical or physical properties of substances involved in industrial processes. It provides real-time data to monitor, control, and optimise production. A process analyser goes through the following steps: The analyser automatically takes a representative sample from the process stream. It conditions the sample, if necessary (e.g., cooling, filtering, or diluting). The instrument applies an analytical technique such as titration, spectroscopy (Raman, NIR, XRF), photometry, or ion chromatography. The analyser calculates the concentration or property of interest and sends the result directly to the plant’s control system (PLC, DCS, or SCADA). This allows operators to monitor product quality, optimise efficiency, and ensure safety and compliance without waiting for laboratory results.

A process analyser is an instrument that measures the chemical or physical properties of substances involved in industrial processes. It provides real-time data to monitor, control, and optimise production.

A process analyser goes through the following steps:

The analyser automatically takes a representative sample from the process stream.
It conditions the sample, if necessary (e.g., cooling, filtering, or diluting).
The instrument applies an analytical technique such as titration, spectroscopy (Raman, NIR, XRF), photometry, or ion chromatography.
The analyser calculates the concentration or property of interest and sends the result directly to the plant’s control system (PLC, DCS, or SCADA).

This allows operators to monitor product quality, optimise efficiency, and ensure safety and compliance without waiting for laboratory results.

Laboratory ion chromatography (left) and process ion chromatography (right) are suitable in different situations, depending on the end-user requirements..

Manual sampling takes time, requires handling of hazardous chemicals, and delays decisions. A process analyser measures directly in the process, delivering accurate and continuous results without waiting for laboratory analysis. This reduces errors, improves product quality, increases efficiency, and protects operators from exposure to hazardous samples.

Blog: Laboratory vs. process analysis: Key factors for informed decision-making

The following table compares process analyzers to laboratory analyzers:

Feature	Process analyzer	Laboratory analyzer
Location	Installed directly in the process	Located in a separate lab
Measurement frequency	Continuous or at set intervals	Periodic, depending on manual sampling
Response time	Real-time results	Delayed results after transport and analysis
Accuracy	High, suitable for process control	Very high, suitable for detailed analysis
Safety	Reduces manual handling of hazardous samples	Requires operators to handle samples
