Coating of GC Stationary Liquid in Volatile Solvents by Standing and Natural Drying Method

GC stationary liquid was coated in n-hexane,acetone or some such volatile,low viscosity solvents.The carrier was dipped into the solvents in a proper proportion that it could just be wet without excess solvents. Rotating evaporator,water bath,infrured lampagitation and heating were not required. The advantages coating in this way were easy to do,quick to coat,personally safe for the operators and less carrier broken.A homogeneous coating can be readily achieved.The volatile solvents in which common GC stationary liquids were coated were tabulated.The proportions of the stationary liquids to the solvents were also advised in this paper.
