Abstract
Surface on which samples are to be precipitated for detection by internal reflection spectroscopy of impurities of liquid aerosols and vapour in a gas, is coated with a finely divided inorganic powder, transparent to reflective radiation and having a refractive index lower than the main body and a particle size smaller than the wavelength of the radiation used.
