The adsorption enthalpy of the Sg dioxydichloride on a quartz surface ((SgOCl)) has been reported to be -98 kJ/mol. The result, however, is still ambiguous because the value was evaluated based on a few experimental points with large statistics errors. To obtain a reliable (SgOCl)) for a discussion of an influence of relativistic effects, a stable gas chemistry apparatus with good reproducibility is mandatory. In this study, we have conducted offline experiments of an isothermal gas chromatography) with short-lived Mo isotopes originated from a Cf fission source. We searched for experimental parameters for an on-line experiment. At the presentation, we will present the obtained optimum conditions for gas chromatographic separation of group-6 elements and determined (MoOCl)).
