With Iatroscan MK6 you can characterize Petroleum and Bitumen in only 30 seconds.
Iatroscan MK6 is quick, precise and unexpensive!
Even if there could be other SARA Analysis alternatives, including IP 143 followed by preparative HPLC (IP-368) or Clay-Gel (ASTM D-2007), these are much more complicated and slower.
A quick sample preparation and... not days or hours, just a few seconds. SARA analysis can apply to many components of crude oil. Asphaltenes could be pentane-or heptane-insolubles.
The best technology on the market for Petroleum and Bitumen analysis. Iatroscan is not only Sara analysis: with Iatroscan you can also get Wax percentages in a flash!
Resins may be classified as a solubility fractions, such as heptane-soluble and pentane-insoluble or heptane-soluble and acetone or ethyl acetate insoluble, or as the polar fraction eluted from a polar adsorbent with a polar solvent, such as pyridine, toluene or methanol.
Saturates and Aromatics are determined by adsorption chromatography, through our patented Chromarod silica gel bars. Saturates are eluted with a paraffinic solvent, such as pentane or heptane. Aromatics are eluted either with paraffinic or moderately polar solvents, such as toluene. Iatroscan standard method is IP 469 which determines all four compound classes by adsorption chromatography.
