I. Summary
The instrument is designed and made as per the national standard of People's Republic of China GB/T17144 Test Method for Carbon Residue of Petroleum Products by Micromethod. It is suitable to determine the carbon residue of petroleum products.
The range of carbon residue determined with the instrument:0.10%(m/m)～30.0%(m/m). To the products which carbon residue exceed 0.10%(m/m),the test result is equivalent with the carbon residue tester(Conradson Method).
The instrument is also suitable to determine the petroleum products composed of distillate oil which carbon residue is lower than 0.10%(m/m).But it should prepare 10%(V/V)distillation residue by method of GB/T6536 firstly and then doing determination with the instrument.
