摘要
通过对非散射红外法测定卷烟烟气气相中一氧化碳含量的分析,从测量重复性、一氧化碳示值、抽吸口数、抽吸容量及大气压力和温度等方面计算测定过程的不确定度分量,并计算相对合成标准不确定度和扩展不确定度,达到了对该方法测定一氧化碳的测量不确定度评定的目的,在一定程度上反映了实验室的检测水平。
By analyzing the scattering infrared spectrometry cigarette smoke gas phase analysis of carbon monoxide levels,from repeatability,carbon monoxide the over-error of indication,suction mouth number,suction capacity and atmospheric pressure and temperature measuring process etc calculation uncertainty components,and calculating the relative synthetic standard uncertainty and expanded uncertainty,reached for the method for determining carbon monoxide measurement uncertainty evaluation purpose,to a certain extent,reflected the laboratory detection level.
