Tobacco quality

It is possible to differentiate various tobacco types fast with spectral imaging. This gives you the chance to varify the purity of your tobacco. 

Tobacco segmentation example

Tobacco samples with cut tobacco leaves, stalks and flakes Sample 1: Tobacco types with cut tobacco leaves, stalks and flakes

Below is an example of a tobacco sample shat has been segmented with spectral imaging in the VideometerLab. The sample contained 3 constituent types of tobacco: leaves, flakes and stalks.

  • It was possible to discriminate the three classes spectrally for automatic quantification.
  • As delivered the three samples had different structure - especially type 2 was a loose grainylike material while type 1 and 3 was entangles material.
  • Because of the structure the delivered samples were not homogeneous mixtures but heterogeneous mixtures. Presented as done here type 1 and 3 were overrepresented in relation to type 2.
  • To create the best and most representative quantification of constituents the samples could be cut into a finer grainy structure and mixed before analysis.
  • Note: The grainy material could have been fed automatically into the VideometerLab using an automatic feeder.
