sensitive Formicaldehyde gas instrument

1996-8-1The present instrument dispenses with the use of infra-red by employing visible light along with a gas-sensitive polymer which changes colour in the presence of CO 2, this being a reversible process. The instrument itself also utilises a novel realisation of the well-known double-beam-in-time principle in which fibre-optic light guides replace ...

The wavelengths from the optical source can be separated spatially using prisms or diffraction gratings. This is known as dispersive separation. Alternatively, an optical filter can be used which allows only transmission of the required wavelength. This is a non-dispersive infrared (NDIR) approach. It has been shown (Jacquinot P. 1954 J. Opt.
