2035 Process Analyzers
The 2035 Process Analyzer is a versatile wet-chemical analyzer which comes in three basic configurations for potentiometric, photometric, and thermometric determinations.
The 2035 Process Analyzer is an integrated solution for 24/7 online monitoring of critical chemical parameters in industrial processes and wastewater streams.
- 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
Customization for any situation
To help further automate your analysis, Metrohm Applikon manufactures sample preconditioning systems such as
and much more.
Burets or pumps can be chosen in the analyzer 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 Analyzer for further customization. Shelters and other specialized 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 color and turbidity are eliminated by the use of differential measurements taken before and after the addition of a color 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 analyzed 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.
2035 Process Analyzer - Thermometric
The 2035 Process Analyzer for Thermometric Titration performs automated titrations with a fast-responding, highly sensitive temperature sensor. Instead of the electrochemical potential, the endpoint is determined by enthalpy, i.e., by change in temperature of the solution during the titration. Thermometric titration is by far the most robust titration method available on the market and is excellent for 24/7 online process applications, such as the monitoring of etching baths. No sensor calibration is necessary, and less cleaning steps are needed. Rapid analysis is possible with this technique; acid mixtures, e.g., can be analyzed in less than three minutes.
Thermometric titration can be used for a wide variety of titration analyses and is well-suited to handle aggressive sample matrices because of the robust thermometric sensor. The sensor needs no maintenance because fouling and other undesired interactions are minimal, and there are no membrane or diaphragm problems as with other titration methods. Thermometric titration is a problem solver for difficult samples which cannot be titrated potentiometrically, and is also a preferred technique in situations when HF is present in samples.
2035 Process Analyzer - Photometric
The 2035 Process Analyzer for Photometric Measurements includes a compact photometer module which is stable over a large concentration range, and is thermostated with stirrer capabilities. This analyzer is offered with two options: a cuvette system or a fiber optic dipping probe. The cuvette system is compact in order to reduce reagent consumption, yet it offers a long optical path length for high sensitivity. The fiber optic immersion probe broadens our application range substantially by making the accurate measurement of high concentration samples simpler through the use of internal sample dilution steps and a smaller light path than the cuvette system.
Photometric analysis is a common, widely-used technique which can determine ions such as ammonia, manganese, and iron in drinking water or even calcium and magnesium in brine solutions. Undesired sample matrix effects such as sample color or turbidity can be removed with differential measurements, taken before and after the addition of a color reagent.
2035 Process Analyzer - Potentiometric
The 2035 Process Analyzer for Potentiometric Titration and Ion-Selective Measurements performs analyses with dedicated electrodes and titrants. Additionally, this version of the 2035 Process Analyzer is also suitable for Ion-Selective Analysis using Metrohm high performance electrodes. This accurate standard addition technique is ideal for more difficult sample matrices.
The potentiometric version of the analyzer offers the most accurate results of all measuring techniques available on the market. With far more than 1000 applications already available, titration is also one of the most used methods for analysis in almost any industry for hundreds of components varying from acid/base analysis to metal concentrations in plating baths.
Titration is one of the most widespread absolute chemical methods in use today. The technique is straightforward with no need for calibration.
