A gas-jet system is described which has been installed at one of the external beam lines of the reactor SAPHIR. By means of a Boral chopper between the target chamber and beam line timed production of fission products can be achieved. In a first experiment this gas-jet system was used to develop a continuous and fast separation for short-lived isotopes of niobium with half-lives down to 7 s using isothermal gas chromatography in quartz columns. As reactive gas HBr^ j was used.
