Many applications. The reliability of the oxygen vessel method has led to its acceptance as the basic procedure for determining sulfur, halogens and other elements in a broad range of combustible materials, particularly:

Sulfur in coal, coke and refuse derived fuels.

Sulfur in petroleum products.

Chlorine in petroleum and other combustible samples.

Other halogens and elements such as: arsenic, mercury, phosphorus and boron can also be determined by oxygen vessel methods. Heavy metals present as trace elements in combustible samples can be determined by adding a quartz liner. A full discussion of oxygen vessel methods, including a listing of standard ASTM, ANSI, API, IP test procedures and an extensive bibliography is provided in 207M Analytical Methods for Oxygen Bombs.
