title: Potentialities of infrared spectroscopy in determining traces of carbon or oxygen as carbon dioxide.
abstract: The determination of traces of carbon dioxide by infrared spectroscopy has been investigated. For maximum sensitivity the absorption band at 2350 cm(-1) is measured, the total pressure being raised to one atmosphere by addition of an inert gas. With a micro gas-cell and a beam-condenser the limit of detection is 0.02 mug of carbon, and for 4, mug of carbon the coefficient of variation is 1.5%.
