Perspective for the determination of chemical properties of element 112

Results of thermochromatographic model studies with Rn and Hg, conducted in order to prepare future gas-adsorption chromatographic investigations of element 112 are represented. The adsorption properties of Rn on various transition metals were investigated by vacuum thermochromatography. From the results of these experiments predictions have been deduced for the adsorption behavior of hypothetically noble-gas-like elements 112 and 114. Empirical predictions of the adsorption interaction of a noble metallic element 112 and its homologues with transition metal surfaces are given in literature. The results of these calculations are compared with experimental data obtained in thermochromatographic model experiments with Hg. The most efficient way to chemically identify element 112 is the use of a cryo-on-line detector. Modifications of this device, needed for the on-line thermochromatographic investigation of element 112 are presented together with results of lest experiments with short-lived isotopes of Rn and Hg
