within the liquid phase. However, during storage, transport, or agitation, this dissolved gas readily migrates out of the liquid and accumulates in the "headspace" or ullage of a storage tank. A relatively low concentration in the liquid phase can evolve into thousands of ppm within an enclosed vapor space. Regulatory Compliance

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.
