Summary
   This instrument is based on the industry standard of the people's Republic of China 0509-2010 JTG and ASTM D4124 "petroleum asphalt four-component determination method" ,JTG E20-2011 Standard Test Methods for Bitumen and Bituminous Mixtures for Highway Engineering in T 0618-1993 "Asphalt chemical composition test (four-component method)" provides the design and manufacture of it. It is the ideal instrument for measuring petroleum asphalt saturate, aromatic, resin and asphaltene four components.
   The instrument can also refer to People's Republic of China industry standards SH / T 0266-1992 (1998) " Petroleum asphaltene content determination method" to measure diesel, fuel oil, lubricating oil, asphalt and remove low boiling point fractions of crude oil asphaltene before 260 ℃.
