Parr adiabatic calorimeter containing a Parr double-valve oxygen combustion bomb. The water equivalent of the calorimeter was determined from the combustion of a weighed sample of benzoic acid standardized by the National Bureau of Standards (NBS). The agreement between results of any two acceptable runs was better than 0.10%.

Commercially available systems such as the Parr oxygen combustion bomb (Paar Instmment Company, USA) and the Bioklav pressure decomposition device (Siemens, Germany) can be employed for sample preparation applications. 

The Parr oxygen combustion bombs were used for a rapid ash determination and for sample preparation for IC. About 0.5 g of shale or shale oil was mixed with 0.5 g of white oil in a stainless steel cup. Five mL of water was placed in the bottom of the bomb which was then assembled and pressurized to 30 atmospheres of oxygen. After combustion, the bomb was allowed to cool for ten minutes and then opened slowly. The inside walls of the bomb were washed with water, and all the washings were combined, filtered if necessary, and diluted to 50 mL. The residue in the cup was dried at 110°C for 15 minutes and reweighed for ash determination.
