|Brief description: || |
The oil sample is burned at a temperature of 1,000 °C with the addition of oxygen. The combustion gases are flushed into the titration cell with the gas flow. Among other things, this cell contains a silver electrode in an electrolyte solution. If the combustion gases contain chloride ions, the ions react with the silver ions. This reduces the silver concentration of the solution, and the current must be increased to compensate for the loss of silver ions in the solution.
Once the chlorine has reacted fully, the measurement is complete. The chlorine content of the sample is calculated from the current consumed for the measurement.
