concentrations in the equilibrium headspace of a sample, which is essential for ensuring both and product quality control in refineries and fuel terminals. Scope and Application astm d5705 pdf
The primary purpose of ASTM D5705 is to determine the vapor phase concentration of hydrogen sulfide (H₂S) in crude oil. This is distinct from measuring total sulfur content; this test specifically looks at the dangerous gas that accumulates in the air space above the liquid oil. and agitated on an orbital shaker at 220
