Oxygen Parr bomb

A PET oligomer isolation method has utilised chloroform extraction in a Parr bomb lined with a Teflon-TFE fluoro-carbon resin [40]. The analytics of fluoropolymer processing aids (combustion analysis, XRF, EUR, 19F NMR, OM) have recently been described [29]. Combustion analysis (Parr Oxygen Bomb Calorimeter) can be used for quantitative analysis... 

Parr calorimetric bombs and calorimeters are very much in use in the US. These bombs are cylindrical in shape and are provided with covers which can be securely closed against leakage. Detailed descriptions of experimental procedures using Parr oxygen bombs and Patr calorimeters... 

The Parr oxygen bomb can be used if only a rapid ash determination is desired. The residue left in the ignition cup is equivalent to the ash content of a given shale. Having... 

Proximate analyses of the fuel and char were run using a standard laboratory drying oven, muffle furnace, and analytical balance according to ASTM Standard Methods. Ultimate Analysis for percent C, H, N, S, and O in the fuel char, and condensate was conducted by the Chemistry Department, University of California, Berkeley. The energy content of the fuel and char was determined with a Parr Oxygen Bomb Calorimeter. 

All major ash elements and some trace elements are determined in coal or fly ash by inductively coupled plasma emission spectrometry. Parr oxygen bomb combustion followed by ion selective electrode. X-ray fluorescence or atomic absorption spectrom-etric measurements are used to determine halogens, sulfur, nitrogen, mercury, arsenic, selenium, and phosphorus. Hydride generation-atomic absorption spectrometry is used to determine traces of As,...
