| 摘要 |
The present invention relates to a method for evaporating a thin film chromatography developing solvent, in which a material to be analyzed is developed on an adsorption agent thin film of a developing support (60) using a developing solvent and the developing agent is developed on the adsorption agent thin film and, more particularly, to a method for evaporating a thin film chromatography developing solvent, in which a nitrogen vortex is formed to be adjacent to the developing support (60), thereby evaporating the developing solvent through the nitrogen vortex. The present invention is especially useful in SARA analysis of oil, and this is because the oil includes aromatic series, resins, and the like. It is preferred that the nitrogen vertex is formed by spraying nitrogen into a chamber (10), in which the developing support is charged, at a flow rate of 0.5-1.0 L/min, and it is preferred that the pressure in the chamber at this time is 1.2-1.5 atm. |
