Autosampler for ESR/EPR sepctrometers

The autosampler provides the means for automatic insertion of sample tubes into the inlets. Manual insertion of the sample is possible but is no longer common. Automatic insertion provides better reproducibility and time-optimization.


Everyday analytics in research labs and industrial quality control requires sample throughput beyond the capability of an individual. This is enabled by a variety of autosampler configurations for liquids, solids and powders. Even mixing of components within the resonator is possible following chemical reactions. Ask us for customized integration in your workflow.

Autosampler for powder and solid samples

Automated handling of quarz tubes & precise height positioning within resonator for highest reproducibility

  • 26 sample positions

  • sample tubes: 165 mm long, 3 to 6 mm diameter

  • option to combine with automated goniometer

Autosampler for Alanine dosimetry

Automatic handling of alanine pellets is a standard add-on for MS 5000 alanine dosimetry system. Operated through ESRStudio, a sequence of sample placement and measeurement is followed. Measured data is saved automatically. The alanine autosampler ensures high throughput by:

  • huge capacity: 55 alanine pellets

  • automatic measurement data collection & storage

Autosample for liquids (Beer Analysis Technique)

Due to the chain reaction of beer-derived free radicals, carbonyl end products like aldehydes and ketones are created, which cause the staling of beer. However, the endogenous antioxidants inhibit the free radical oxidation until they are depleted. Hence this free radical oxidation can be minimized by optimizing brewery operations and storage conditions to provide a maximum antioxidant content on the packaged beer. At each stage of the brewing process the comprehensive antioxidant status of the beer/beverage can be detected by ESR measurements and the determination of the EAP- and BAX value. That way, the shelf life and flavor stability of a finished beer can be determined at the individual stages of the brewing process e.g. before packaging and distribution.


  • Fully automated handling of samples

  • Up to 30 samples per analysis

  • Temperature control up to 70°C

  • Automatic EAP and BAX calculation

  • State-of-the-art and user friendly software
