A high speed micro vacuum-fusion apparatus.
A micro vacuum-fusion apparatus capable of extracting, collecting and examining volumes of gas of no more than 2 x 10(-3) cm(3) at N.T.P. from metal samples is described. The resulting gas mixture is analysed by gas chromatography with helium as the carrier gas and with a highly sensitive ionization detector.
