浓香型白酒酒精度检测能力验证研究

Study on Proficiency Testing of Determination of Alcohol of Luzhou-flavor Liquor

在酒精度检测能力验证项目中,多数实验室采用密度瓶法,少数实验室采用酒精计法、气相色谱法和数字密度计法。在能力验证中,采用密度瓶法和数字密度计法实验室满意结果比率较高,采用气相色谱法实验室满意结果最低。酒精度检测是一个对操作细节要求特别严格的项目,因此,应严格按照国标中规定进行操作,尤其注意操作中温度的掌握。

In the project of proficiency testing of determination of alcohol,the majority of laboratories adopted pycnometric density,a small number of laboratories adopted alcoholmeter,GC and DCD Digital Computing Densitometer.In this proficiency testing,laboratories which adopted pycnometric density and DCD Digital Computing Densitometer acquired higher rates of satisfactory results,the satisfactory results of laboratories which adopted was lowest.Determination of alcohol was a project of particularly stringent requirements for the operational details,therefore,it should be strictly operated in accordance with the provisions of the national standard,especially controled the temperature in operation.
