    If the sample explodes then some sample material is settling unburned on the vessel wall (which makes the result useless) and the pressure rises too high which is un-safe. Therefore: DDS CALORIMETERS OPERATIONS MANUAL V1.1 2022 Website:...

    Should the Oxygen supply be in another room, make sure there is a high pressure shut off valve near the CAL3K calorimeter. Start the oxygen regulator at a very low (Adjustor turned OUT) reading and then adjust it until 30bar = 3000KPA is indicated on the gauge.

  • Page 28: Calibration

    It is therefore imperative that the calibrations are performed at different operating conditions like: First/last time in a day During routine operation Whenever the operating conditions have changed Whenever parts (consumables) of the vessel have changed DDS CALORIMETERS OPERATIONS MANUAL V1.1 2022 Website: www.ddscalorimeters.com...

    The result (and calibration) quality is judged by the compensation amount in Degree C. See: COMPENSATIONS. The compensations are judged by: A) Total compensation. The sum of all compensations: Total Compensation B) The ABSOLUTE sum of all compensations: Maximum Compensation DDS CALORIMETERS OPERATIONS MANUAL V1.1 2022 Website: www.ddscalorimeters.com...
  • Page 30: Average Calibration

    A ‘ZERO’ entry (Default) disables the acceptance check. A practical example: Average calibration: 2 Average acceptance: 0.024 Then the average will be performed with THREE calibrations if all are excellent to go. DDS CALORIMETERS OPERATIONS MANUAL V1.1 2022 Website: www.ddscalorimeters.com...
  • Page 31: Calibration Summary

    The ‘Spike’ must be of a known calorific value, usually benzoic acid of approx. 26.454MJ/Kg. On some occasions a Gelatine Capsule (3k-4-068) or Crucible Cover Disc (CAL2K-FLDS) needs to be used as a Spike. DDS CALORIMETERS OPERATIONS MANUAL V1.1 2022 Website: www.ddscalorimeters.com...
  • Page 32: Spike Value

    This is the spike mass. If the value is >0 the spiking is assumed and the result will be reduced by: Spike mass x Spike value. The spike mass is cleared after a determination. A ‘ZERO’ spike mass disables the spiking process. DDS CALORIMETERS OPERATIONS MANUAL V1.1 2022 Website:...
  • Page 33: Step By Step Entering The Spike Mass

    Of course, you can determine the average CV of let say 10 capsules. The Temperature Rise of each determination must be read out via the keyboard (CMD=36) and then averaged and entered via CMD=29. The EASY SPIKING is enabled via: GELATINE CAPSULE DDS CALORIMETERS OPERATIONS MANUAL V1.1 2022 Website: www.ddscalorimeters.com...
  • Page 34: Corrections

    If the sample contains sulphur then energy is released during the formation of SO2 from oxygen and sulphur. This energy is deducted from the nett CV. The sulphur content of the sample must be measured before and the CV (KJ/g) of SO2 formation must be entered: DDS CALORIMETERS OPERATIONS MANUAL V1.1 2022 Website:...
  • Page 35: Moisture Correction

    Then the temperature rise caused by a gelatine capsule is entered here (Default=2.594). This entry is associated with the capsule (Manufacturer, weight, size) and is constant unless changed. If a capsule is used (for powdery samples) then is must be enabled with CMD=28. DDS CALORIMETERS OPERATIONS MANUAL V1.1 2022 Website:...
  • Page 36: Firing

    These compensation factors change with: Vessel construction: Deflector plate, Crucible holder, firing wire length, cotton length CAL3K construction: Ambient temperature, ATC temperature (if installed), Ventilation Vessel age and surface condition DDS CALORIMETERS OPERATIONS MANUAL V1.1 2022 Website: www.ddscalorimeters.com...

  • Page 38: Limits

    A limit can be set up to warn the operator that the sample mass was too low. The default setting is 8C. A lower rise can be achieved by calibrating the unit to an 8C+-2C. It is just difficult to split a Benzoic Acid tablet to 2/3. DDS CALORIMETERS OPERATIONS MANUAL V1.1 2022 Website:...
