Synthesis and gas chromatographic use of metal-containing surfaces

摘要: Abstract A variety of volatile metal halides were used in the gas phase to produce layers with thicknesses monomolecular range on Chromosorb W. The final result from subsequent treatment H 2 O, NH 3 or . They could be considered “oxide”, “nitride” “reduced” type, although no evidence for particular surface structures has been obtained. Layers tested by chromatography directly and after attempted synthesis an additional “bonded” Carbowax 20M layer. These procedures successful (in terms achieving inorganic good 20M) some but not all cases. best materials about equal chromatographic performance comparable phases containing metals. “Bonding” achieved several types layers. For example, those Fe Cr performed noticeably better than Al B. General uses such are suggested.
