| Abstract: | In this paper, performance and application of a new low pressure and exponential gradient thin coated gas chromatographic column have been investigated. Optimum column pressure( P ), plate height( H ), resolution( R ), tailing factor ( T ) and resistance coefficient of mass trunsfer( H_u ) were determined. The results show that the column is characterized with low column pressure, low column temperature, rapid and high efficiency. The column was applied to the separation of divers alcohol with satisfactory results. |
