Beschreibung
Zusammenfassung:	The invention discloses a method for measuring an oil-washing distillation range, which belongs to the field of coal chemical industry. In the method, distillation amounts before 230 DEG C, 270 DEG C and 300 DEG C in an oil-washing process are calculated by capillary chromatography. The method has the advantages of high accuracy, small system error, short analysis time, high full automation degree and capabilities of preventing personnel from contacting a large quantity of toxic samples and toxic steam and ensuring the health of the personnel.
