摘要：

For better stability the gas chromatographic stationary phase Carbowax 20M is often immobilized on different support materials. Some physico-chemical properties of siliceous supports with thermally immobilized Carbowax 20M are described. The results obtained point to the formation of acidic groups (centres) in the Carbowax layer during its immobilization procedure.
