Gas-chromatograpbic studies on the distribution of tritium in labelled toluene. The distribution of tritium in tritiated toluene was measured by preparing appropriate nitro-derivates. These were separated on gas-chromatographic columns. The substances were identified by thermal conductivity measurements, simultaneously the H$^{3}$ activity was recorded by a gas counter. For the high-boiling substances it was necessary to run the gas chromatograph and the counter at temperatures up to 220° C. In consequence considerable analytical difficulties had to be overcome. lt was found that the addition of nitrobenzene to the counting gas, which consisted of helium and methane, proved to be especially useful. The results of various labelling methods are compared and discussed in the light of current research. |
