A micro-bomb calorimeter exploded when the wrong proportions of sample and oxidants were used. Instead of 4 g of peroxide and 0.2 g of nitrate for 0.2 g of the sugar sample, 0.35 g of peroxide and 2.6 g of dextrose were used. The deficiency of peroxide to absorb the decomposition gases and excess of organic matter led to a rapid rise in temperature and pressure, which burst the bomb calorimeter. 

The Parr Co also manuf "peroxide bombs . These bombs are small pressure vessels in which samples are subjected to the intense oxidizing action of Na peroxide at a temp high enough to completly burn almost all C compds. Powdered K perchlorate and other reagents can be used together with peroxide to assist and accelerate ignition and to carry the reaction to completion (See Parr Specification No 2000)... 

In the present work, twenty-seven of these oils were separately analyzed for sulfur content and sulfur isotope ratio (Parr Instrument Company bomb. Sulfate in washings from the bomb were precipitated with Ba2+. The BaSOA precipitate served for gravimetric determination of the S-content conversion to S02 for mass spectrometry (4). The 3AS/32S abundance ratios are presented in the usual 63AS notation. 

A sample of nitronate (0.8 g) was heated in a titanium bomb in 10°C increments from ambient temperature. Under adiabatic conditions the nitronate began to selfheat at 70°C and violently deflagrated at 106°C (Figure 3). The deflagration produced temperature rates of 700°C/min, pressure rates of 6000 psi/min, and nitrogen oxide off gases.
