Automatic injection of the samples into the gas chromatograph allows up to 36 samples to be run overnight thus saving valuable technical time. The method described can easily be adopted for use in a routine steroid laboratory. The results obtained by this method have been compared with values obtained by the method of Klopper, Michie, and Brown (1955).
