Development of an Apparatus for Seaborgium Studies by High Temperature Gas Chromatography

In preparation for the characterization of Sg as oxide hydroxide a new high temperature gas chromatography apparatus based on the OLGA design was developed. However, the time-consuming recluster step was replaced by direct deposition of species leaving the chromatographic column on metal foils. In test experiments with short-lived Mo isotopes a retention time of 9 s was determined for an isothermal temperature of 1270 K, sufficient to study Sg isotopes.
A model based on the theory of supersonic jet and on simple geometrical considerations reproduces the data of direct condensation experiments quite well.
