摘要
An apparatus and method (and related kit) for determination of the isotopic ratio of 13C to 12C in a gas sample containing carbon dioxide comprising introducing gas into a gas sample chamber, directing light into the sample chamber from a laser light source, the laser light source being capable of accessing one or more of the wavelength pairs 2054.37 and 2052.42; 2054.96 and 2051.67; or 2760.53 and 2760.08 nanometers, and with a detector detecting the laser light energy after passage through the sample chamber.
