Abstract
A method for detecting the presence and amount of carbon monoxide, comprising the use of infrared spectroscopy to compare the spectra of the test gas containing carbon monoxide and the reference gas. The reference gas is the test gas from which carbon monoxide had been removed by conversion using catalysts. The presence and quantity of carbon monoxide is determined by deducting the spectrum of the reference gas from the spectrum of the test gas. The catalysts comprise nanoparticles of gold precipitated on a metal oxide or hydroxide carrier. An apparatus implementing this method.
