ProUmid GmbH: SPSx high capacity multisample moisture sorption analyser

GVS of rice grains with SPS11-10u

The SPSx instrument is a multisample Gravimetric Sorption Analyser, capable of simultaneous measurement of DVS isotherms on up to 23 samples. It allows the user to choose between two different configurations:

  • 11 samples with a large sample weights for representative sampling of materials with large granularity or low homogeneity, or
  • 23 smaller samples with maximum precision and weighing resolution, for maximum throughput.

Both options are supplied with the SPSx instrument.

Simultaneous measurement of all samples proceeds in parallel, at temperatures from 10 °C to 60 °C. Humidity is controlled from Dry to 98% RH at temperatures close to ambient, with a lowered maximum value at higher temperatures.

Different microbalance options are available, according to the required measurement precision and sample weight. Versions are available for up to 200 g maximum load, and for weight resolution down to 1 µg for small samples.
