B. Ulrich,N. Kockel,G. Holbache of this, difficulties are continually arising in the experimental realization of this interesting development of gas chromatography, and this hinders the rapid acceptance of these methods. For this reason, in the present work I have dealt with experimental and practical problems rather than with t

K.-H. Fuchs,R. Engemann,A. Thiedeg is continually changing, and it is necessary at the first stage of separation to carry out the ‘development’ and the preliminary evaluation of the chromatogram at one and the same time. Special instruments are needed to record the separated substances, because, generally speaking, in gas chromatog
