Abstract : The results of the measurements carried out on nitrogen and oxygen are given. Sensitivity of the order of 10 to the -10th power was achieved with the refractometer, but its use at such sensitivities is very delicate and required many precautions. At reduced sensitivity, i.e. at smaller synchroscope sweep velocities, the use of the refractometer was quite simple and satisfactory. Accurate measurements can be performed at sensitivities of 5.10 to the -9th power or lower. At present, the main use at higher sensitivities will be to detect small sudden changes of the refractive index. (Author)
