| Abstract: | Summary The influence of the film thickness of Carbowax 20M coated onto glass surfaces (series of columns with different mode of surface treatment) upon the retention indices of solutes which exhibit tendency to hydrogen bonding has been investigated. Limiting values of Kovats indices, I , are calculated for all the columns examined.Presented at the  14th International Symposium on Chromatography London, September, 1982 |
