ASTM D2887 is a test method developed by ASTM International (formerly known as the American Society for Testing and Materials) for the determination of the boiling range distribution of petroleum products by gas chromatography. This test method is specifically used to analyze and characterize the composition of hydrocarbons in a given sample, such as crude oil or refined petroleum products, based on their boiling points.
In the ASTM D2887 test, a sample is injected into a gas chromatograph, which separates the various components based on their boiling points. The detector then records the data, and a chromatogram is produced, showing the peaks corresponding to different hydrocarbons. By analyzing these peaks and their positions on the chromatogram, you can determine the boiling point distribution of the sample, which is useful for quality control, product specification, and research and development in the petroleum industry.
