Abstract: A source of IR radiation for use with a gas analyzer comprises a sealed-off enclosure (4) containing at least one molecular, IR-active gas which, upon excitation, is capable of emitting IR-radiation of a known, discrete spectral distribution. The excitation is effected by electrical discharges taking place in a limited portion (32) only of the sealed-off enclosure (4), the rest of the enclosure serving as reservoir (34) of the gas. The electrodes (20) producing the discharges are disposed outside of the enclosure (4). A gas analyzer (2,4,6,8,10,12) incorporating the source is also described.
