5 Operating Instructions Chapter 5 Operating Instructions Operating the 1108P Oxygen Combustion Vessel Detailed instructions for preparing the sample and charging the 1108P Oxygen Combustion Vessel are given in Operating Instructions No. 418M. Follow these instructions carefully, giving particular attention to the precautions to be observed in charging and handling the bomb.
6100 4. Set the bucket in the calorimeter. Attach the lifting handle to the two holes in the side of the screw cap and partially lower the bomb in the water. Handle the bomb carefully during this operation so that the sample will not be disturbed. Push the two ignition lead wires into the terminal sockets on the bomb head. Orient the wires away from the stirrer shaft so they do not become tangled in the stirring mechanism.
5 Operating Instructions Combustion Aids Some samples may be difficult to ignite or they may burn so slowly that the particles become chilled below the ignition point before complete combustion is obtained. In such cases benzoic acid, white oil or any other combustible material of known purity can be mixed with the sample. Ethylene glycol, butyl alcohol or decalin may also be used for this purpose.
6100 Operating Instructions Figure 5-2 Figure 5-3 Figure 5-4 3601 Gelatin Capsules 43A6 Combustion Capsule with Adhesive Tape Seal 43AS Combustion Capsules Capsules should be monitored for wear. Do not use the capsule if the wall or base thickness is less than 0.025”. New capsules are heated in a muffle furnace at 500 ºC for 24 hours to develop this protective coating uniformly on all surfaces.
5 Operating Instructions Explosives and High Energy Fuels The 1108P and 1108PCL vessels used in the 6100 Calorimeter have been designed to provide highly automated testing of routine samples. Materials which release large volumes of gas which detonate with explosive force or burn with unusually high energy levels should not be tested with these bombs. Rather, they should be tested in a model 1104 High Pressure Oxygen Combustion Vessel designed specifically for these types of samples.
6100 Volatile samples are defined as one with an initial boiling point below 180 ºC per ASTM D-2. Low volatile samples with a high water content, such as urine or blood, can be burned in an open capsule by absorbing the liquid on filter paper pulp or by adding a combustion aid, such as ethylene glycol.
6 Corrections & Final Reports Chapter 6 Corrections & Final Reports Entering Corrections and Obtaining the Final Report Final reports for each test can be obtained whenever the operator is prepared to enter any required corrections for fuse, acid and sulfur. When entering corrections, the user can choose either of two methods.

9 Maintenance & Troubleshooting Chapter 9 Maintenance & Troubleshooting Oxygen Bomb Under normal usage the 1108P Parr Oxygen Combustion Vessel will give long service if handled with reasonable care. However, the user must remember these bombs are continually subjected to high temperatures and pressures that apply heavy stresses to the sealing mechanism. The mechanical condition of the bomb must therefore be watched carefully and any signs of weakness or deterioration should be replaced before they fail.
6100 Maintenance & Troubleshooting 6100 Calorimeter Error List The calorimeter will run a number of diagnostic checks upon itself and will advise the operator if it detects any error conditions. Most of these errors and reports will be self-explanatory. The following list contains errors that are not necessarily self-evident and suggestions for correcting the error condition. A Misfire Condition Has Been Detected This error will be generated in the event the total temperature rise fails to exceed 0.

B Calculations Appendix B Calculations Calculating the Heat of Combustion The 6100 Calorimeter will automatically make all of the calculations necessary to produce a gross heat of combustion for the sample. However, it is important that the user understand these calculations to ensure the instrument is set up so the calculations match the procedures and the units are consistent throughout the process.
Calculations B 6100 ASTM and ISO Methods Differ Current ASTM, ISO, and British Standard Methods differ on their treatment of the nitric and sulfuric acid thermochemical corrections. ASTM Methods call for titrating the bomb washings to determine the total acid present. This is assumed to be all nitric acid with a heat of combustion of -14.1 Kcal per mole. The amount of sulfur is then determined and converted to equivalents of sulfuric acid. The difference between the heat of formation of sulfuric acid (-72.
B Calculations Acid and Sulfur Corrections • • • Total acid is the amount of base required to titrate the bomb washings (milliliters). Nitric acid is that portion of the total acid in the bomb washings that result when the nitrogen in the air that is trapped in the bomb is burned at high pressure. Since this nitric acid does not result from the sample, and the combustion conditions are reasonably constant from test to test, the amount of nitric acid formed is also constant.
Calculations B 6100 When the Acid Correction is set to Fixed Total the value is considered a final value and the operator is not prompted for an acid value when reporting the results. Entered Total: The Acid Correction represents the total base required to titrate the bomb washings (in milliliters). This includes both nitric and sulfuric acid. The correction is entered by the operator when reporting the results. The calculation is the same as the Fixed Total above.
B Calculations ISO Calculations Both the ISO 1928 and BSI 1016: Part 5 methods for testing the calorific value of coal and coke, deal with acid and sulfur corrections in a manner which is somewhat different than ASTM procedures. Provision has been made in the 6100 Controller for dealing with these different procedures. The analysis of bomb washings in these methods call for a titration, first using 0.1N barium hydroxide (V2) followed by filtering, and a second titration using 0.
Calculations B 6100 When using a spike the total weight of the spike and sample combined should not exceed 1.2 gram. Example 1: A customer is testing glucose (approximate heat of combustion 3800 cal/g) and is having a hard time getting complete combustion. They decide to use benzoic acid for a spike. Benzoic acid has a heat of combustion of 6318 cal/g. The customer would use .7 g of the benzoic acid (4423 calories released) and .
C Standardization Appendix C Standardization Standardizing the Calorimeter The Energy Equivalent Factor The term “standardization”, as used here, denotes the operation of the calorimeter on a standard sample from which the energy equivalent or effective heat capacity of the system can be determined. The energy equivalent, W or EE of the calorimeter is the energy required to raise the temperature one degree, usually expressed as calories per degree Celsius.
Standardization C 6100 Any outliers or other tests which should not be included in the average EE Value must be deleted from the memory using the memory management procedures (see Chapter 8). A list of all tests associated with any Cal ID can be printed from the Calibration Data Page using Print Standardization Runs. The user can elect to have any number of stored standardization runs used in determining the EE value by entering this number on Calibration Data & Controls Page - Calibration Run Limit.
