Abstract
A method of detecting a concentration of contaminants in an air sample. The method includes the steps of combining a first portion of the air sample with a fuel to produce a sample/fuel mixture, igniting the sample/fuel mixture in a combustion chamber to produce a flame, and supplying a second portion of the air sample to the combustion chamber so that at least some of the contaminants contained in the second portion are ionized by the flame.
