Atkinson tube

Later, it was possible to improve substantially the separation of deuterated olefins. Atkinson et al. [67], for example, separated all ethylene isomers differing by one unit of mass. It was shown that the accuracy of the gas chromatographic analysis of deuterium-labelled ethylene isotopes is the same as that in the mass spectral method. Silver nitrate solution in ethylene glycol (5M), saturated at room temperature, was used as the stationary phase [67]. This solution was added to Chromosorb P (45—60 mesh) in the ratio of 1 4 and this mixture was mechanically stirred for 4 h. The sorbent obtained was packed into nylon tube sections of length 15 m and diameter 3 mm. A flame-ionization detector was used.
