Liquid chemicals analyzer

The MB3600-CH20 Laboratory FT-NIR is an accurate, easy-to-use analyzer for determining Hydroxyl Value (HOval) in polyether and polyester polyols, fatty alcohols, pentaerythritol, glycols, EO/PO and related chemistries.



The MB3600-CH20 FT-NIR Analyzer is more than just a robust field-proven analyzer for Hydroxyl Value that replaces costly and time-consuming wet-chemical titration analyses. It is also a powerful method-development platform for applications designed to replace other slow functional-group analytical procedures, in both liquids and solid powder products. 

Reliable Hydroxyl Value Analysis
ABB has been a world leader for many years in industrial FT-NIR analytical solutions. Our Laboratory FT-NIR analyzers are renowned for their ruggedness and long-term stability. This makes them excellent method development platforms for a host of FT-NIR based methods, replacing tedious and expensive wet-chemical procedures.

Rapid Development of Custom Analytical Methods
The MB3600-CH20 is ready to use for the rapid development of custom analytical methods suitable for a wide variety of sample types, including polyester and polyether polyols, polyethylene or polypropylene glycols and amine derivatives.

Quick and Simple Analysis for Fast Product Release
The MB3600-CH20 Laboratory Analyzer simplifies Hydroxyl Value and similar analyses such as Acid Number, Moisture or EO/PO ratio. Analysis is performed using disposable vials which eliminate sample cell cleaning. The measurement time is only 1 minute after the sample has reached the fixed measurement temperature.

Guaranteed Laboratory-to-Process Calibration Transfer
ABB has developed manufacturing methods which ensure all our laboratory and process FT-NIR analyzers are highly stable, have a highly linear photometric response, and provide identical absorbance spectra. This guarantees calibration transferability from lab to process without any additional calibration efforts or data manipulation.



Additional polyol properties can be measured in the same analysis, such as Moisture, Acid Number and EO/PO ratio.

  • MB3600-CH20 results are totally traceable to the reference method and the calibrations are stable, rugged and transferable.
  • Extensively field proven for the rapid development of custom site specific FT-NIR analytical methods. Rugged design and construction combined with superior manufacturing methods guarantee unsurpassed analyzer stability.
  • Results obtained in less than 2 minutes, with simultaneous analysis of Hydroxyl Value and multiple additional properties. Easy-to-use, operator friendly, with very low cost of analysis.
  • Simplified sampling using heated disposable glass vials – no clean up between samples means it is very easy to run large sample batches.
  • Higher analytical precision (increased repeatability, reproducibility and stability) compared with standard wet-chemical methods.
  • Very little training required for use by plant personnel in a routine operations environment.
