“…Higher doses increase the quantity immobilized. The fact that the same percentage of SE-30 appears to be immobilized onto the support, independent of the initial quantity of liquid 18 or of the presence of methyl groups from the silanizing reaction on Chromosorb W-HP, suggests that the immobilization is mainly related to crosslinking of the polydimethylsilane chains rather than to formation of chemical bonds to the support.…”

“…These free radical initiated immobilization methods have been very successful in producing modern high temperature capillary columns. However, very little information exists about immobilization of supported liquid stationary phases for use in packed-column gas chromatography 18 . This investigation was undertaken to investigate the properties of several polydimethylsilanes on Chro-mosorb supports after immobilization by different doses of gamma irradiation.…”

“…Immobilization of the stationary phase is generally achieved by bonding the polymer chain to the support. This immobilization process is initiated by free radicals which are produced by heat [1][2][3][4][5] , chemical initiators such as azocompounds [6][7][8] , peroxides [9][10][11][12][13] or ozone 14,15 , and ionizing radiation such as electrons 16 , gamma radiation 17,18 and low-temperature plasmas 19 . All these methods have been successfully applied to produce immobilized nonpolar silicone phases within capillary columns.…”

“…These prob lems are ame lio rated by the im mo bi li za tion of the sta tion ary phase through bond ing be tween the polymer chains with pos si ble bond ing to the sup port. This immo bi li za tion pro cess is ini ti ated by free rad i cals which are pro duced by heat [1][2][3][4][5] , chem i cal ini ti a tors such as azocompounds [6][7][8] , per ox ides [9][10][11][12][13] or ozone 14,15 , and ion iz ing ra di a tion such as elec trons 16 , γ ra di a tion 17,18 , and low-temperature plas mas 19 . All of these meth ods have been suc cess fully ap plied to pro duce im mo bi lized nonpolar sil i cone phases within cap il lary col umns.…”
