Abstract
A method comprises positioning a sample within an interior volume of a sealable vessel, positioning a first electrode adjacent to the sample such that a first gap is formed between the sample and the first electrode, positioning a second electrode within the interior volume, sealing the sealable vessel, and positioning the sealable vessel within a bomb calorimeter. The method further includes causing an energy to flow between the first electrode and second electrode to cause a reaction in the sample, measuring at least one temperature change within the bomb calorimeter induced by the reaction in the sample, and determining a change in enthalpy via the measured at least one temperature change.

A method for determining change in enthalpy comprising:
- positioning a sample within an interior volume of a sealable vessel;
- positioning a first electrode adjacent to the sample such that a first gap is formed between the sample and the first electrode;
- positioning a second electrode within the interior volume;
- sealing the sealable vessel;
- positioning the sealable vessel within a bomb calorimeter;
- causing an energy to flow between the first electrode and second electrode to cause a reaction in the sample;
- measuring at least one temperature change within the bomb calorimeter induced by the reaction in the sample;
- and
- determining a change in enthalpy via the measured at least one temperature change.
An apparatus comprising:
- a first sealable chamber;
- a second sealable chamber configured to be positioned within the first sealable chamber;
- a pair of electrodes;
- a voltage power source;
- and
- a controller configured to:
- control the power source to cause an energy to flow between the pair of electrodes positioned within the second sealable chamber to cause a reaction in a sample positioned adjacent to a first electrode of the pair of electrodes;
- collect temperature measurement data during the reaction in the sample;
- and
- determine an enthalpy based on the temperature measurement data;
- wherein the energy caused to flow between the pair of electrodes generates an arc across a gap separating the first electrode from the sample.
A method for causing a reaction in a sample comprising:
- positioning the sample within a bomb of a bomb calorimeter;
- positioning a first electrode of an igniter adjacent to the sample;
- spacing the first electrode from the sample such that a first gap is formed between the sample and the first electrode;
- positioning a second electrode adjacent to the sample such that the sample is one of spaced from the sample by a second gap and electrically coupled with the sample;
- sealing the bomb;
- sealing the bomb within the bomb calorimeter;
- controlling a voltage power source coupled with the first and second electrodes to cause an energy to flow between the first electrode and second electrode to cause a reaction in the sample;
- and
- determining an enthalpy change resulting from a reaction of the sample to the flow of the energy.
