The complex allows to determine the group composition of vacuum distillates, fuel oils, tar sands and similar samples. It provides possibility to analyze products in 7 groups:
- paraffin-naphthenes
- light aromatics
- medium aromatics
- heavy aromatics
- resins 1
- resins 2
- asphaltenes
The analysis run time is 40-60 min. depending on the sample being analyzed. The amount of product required for one analysis does not exceed 2 mg.
