Abstract
A gas chromatographic technique in conjunction with a modified Van Slyke apparatus is described for the determination of the Bunsen absorption coefficient (α) for nitrogen in extracted human and dog fats, olive oil, and water. Essentially, the method consists of a double extraction of a sample that has been equilibrated at a stated temperature with a known gas. The liberated gas or gases are then separated and quantified by gas chromatography. The observed Bunsen absorption coefficient (α) for nitrogen in water agrees closely with one of the two sets available in the International Critical Tables at 37.6° C. The present method may also be regarded as accurate for the nitrogen solubility in fats and oils. This accuracy, together with the specificity of the method, supplies new information on the solubility of nitrogen in human fatty material.
