Abstract
To establish the relationship between measured refractivity and gas co ncentration, a measurement system has been developed which can precise ly determine the absolute refractive indices of medical vapours and ga ses at a wavelength of 633 nm. The refractive index of chloroform vapo ur has been measured over the respective pressure and temperature rang es of 1 to 9 kPa and 15 to 40-degrees-C with an uncertainty of better than +/-8 parts in 10(8). The specific refraction and the second viria l coefficient of chloroform have also been derived.
