✦ Synopsis

A method is described for the determination of hydrogen in solid samples. The sample is heated under vacuum after which the evolved gases are separated by gas chromatography with a helium ionization detector. The system is calibrated by injecting known amounts of hydrogen, as determined manometrically. The method, which is rapid and reliable, was checked for a variety of lunar soils, the limit of detection is about 10 ng of hydrogen.

A method has been developed for the gas chromatographic analysis of lipoic acid in biological samples. The lipoic acid is released from the samples by acid hydrolysis in the presence of the internal standatds 1,2-dithiolane-3-butyric acid and/or 1,2-dithiolane-3caproic acid. After hydrolysis, the li
