2035 Process Analysers

The 2035 Process Analyser is a versatile wet-chemical analyser which comes in three basic configurations for potentiometric, photometric, and thermometric determinations.

The 2035 Process Analyser is an integrated solution for 24/7 online monitoring of critical chemical parameters in industrial processes and wastewater streams.

Key features

  • Modular wet part means greater flexibility for applications
  • Additional measuring techniques can be integrated (pH, conductivity)
  • IP66/NEMA 4-rated: protection in harsh environments
  • Customizable, user-friendly interface with several security levels
  • Remote control capability makes evaluating results and inspecting diagnostics easier

Customisation for any situation

To help further automate your analysis, Metrohm Applikon manufactures sample preconditioning systems such as
  • cooling/heating,
  • pressure reduction,
  • degassing,
  • filtration,
  • and much more.

Burettes or pumps can be chosen in the analyser for all liquid handling tasks, and selection valves are implemented for multiple sample streams.

Additionally, a wall mount, table stand, and reagent cabinet are available for the 2035 Process Analyser for further customisation. Shelters and other specialised protection solutions can be custom-built upon request.

Titration made simple

The potentiometric version of the 2035 Process Analyzer offers high selectivity through the use of dedicated electrodes and titrants – no calibration needed.

This potentiometric version is also suitable for Ion-Selective Analysis, which is an accurate standard addition technique ideal for more difficult sample matrices at low concentrations.

With hundreds of applications already available online, you can be assured of Metrohm’s expertise in the field of titration.

Stable photometric analyses

The 2035 Process Analyzer for photometric measurements includes a compact photometer module with a high-performance LED. Both a cuvette module and a fiber-optic dipping probe are offered to broaden the range of applications.

Common interferences such as sample colour and turbidity are eliminated by the use of differential measurements taken before and after the addition of a colour reagent. The thermostated photometer module eliminates sample temperature effects, ensuring repeatable and accurate results with high sensitivity at low concentration levels.

Thermometric titration for difficult samples

Thermometric titration is a problem solver for difficult samples which cannot be titrated potentiometrically and is well-suited to handle aggressive matrices such as HF because of the robust thermometric sensor.

The thermometric sensor requires no calibration and contains no membrane or diaphragm. The endpoint is determined by a change in temperature of the solution during the titration. Rapid analysis is possible with this technique – acid mixtures, for example, can be analysed in less than three minutes.

New: ASTM D8045, released in 2016, describes a thermometric catalytic titration method to measure the Acid Number in crude oil and petroleum products. Using Metrohm thermometric titration, you can speed up your analyses and reduce the amount of solvent required.
