Thus, ALOT columns can be recommended for trace analysis of polar compounds. 4 Uncoated Capillaries as Capillary Adsorption Columns. The properties of uncoated fused-silica capillaries were investigated by some authors in connection with their adsorption activity. But we can also consider uncoated fused-silica capillaries as gasadsorption columns. Therefore it will be interesting to estimate the results of these adsorption investigations. g. [ l , 4, 581). The problem of column wall activity still remains important due to ever-increasing demands on column inertness in quantitative and qualitative analysis.

GSC has two immediate potential advantages over GLC which help to offset the latter’s greater versatility. GSC also has a theoretical potential for handling very difficult analyses and high-speed analyses which, pending the solution of some complex technical problems, might provide up to a rather phenomenal lo7 plates per second. ” One immediate advantage of GSC resides in the fact that a surface with any reasonable degree Chapter 2 22 of uniformity will exhibit a CK* value substantially smaller than the CIof GLC”.
