<p>A combustion analyser sample introduction apparatus and method for supplying a liquid sample into a combustion chamber (130,150) of a combustion analyser. A supply member (108, preferably, cooled) extends through a combustion chamber opening (132,152) and comprises a downstream member end within the combustion chamber. A supply spray head (92) is received in the member end and comprises a discharge opening (94) to deliver liquid sample and carrier gas into the combustion chamber. A carrier gas supply conduit (106,114,122) supplies carrier gas (preferably, oxygen) to the discharge opening, along a carrier gas flow path. A sample supply conduit (100,102) having a downstream first end passes through the supply member towards the spray head and supplies liquid sample into the carrier gas flow path at a sample supply location within the combustion chamber at/adjacent the discharge opening. Liquid sample is thereby transported by carrier gas out of the discharge opening into the combustion chamber as a spray.</p> |
