Combustion analyzer sample introduction apparatus and method

A combustion analyzer sample introduction apparatus for supplying a liquid sample into a combustion chamber of a combustion analyzer, the apparatus comprising:

• a combustion chamber comprising a chamber opening;
• and
• a sample supply apparatus comprising:
• a supply member extending through the chamber opening and comprising a downstream member end disposed within the combustion chamber;
• a supply spray head received in the member end and comprising a discharge opening for delivery of a liquid sample and a carrier gas into the combustion chamber;
• a carrier gas supply conduit arranged to supply a carrier gas to the discharge opening, thereby defining a carrier gas flow path thereto;
• and
• a sample supply conduit having a downstream first end arranged to pass through the supply member towards the supply spray head and to supply a liquid sample into the carrier gas flow path at a sample supply location at or adjacent the discharge opening,
• wherein the sample supply location is within the combustion chamber, such that, in use, a liquid sample is transported by a carrier gas out of the discharge opening as a spray into the combustion chamber.
