Abstract
An apparatus and method for the detection of the growth of microorganisms through infrared analysis of a sample of the gas produced by growth of the microorganism is descirbed. In the method, a sample of the headspace gas in a vial containing a growth medium which has been inoculated with a sample suspected of containing a microorganism is removed and transferred to a sample cell where infrared analysis is used to determine the presence of carbon dioxide, if any, produced by the growth of the microorganism.
