摘　　要：目的:探讨室内空气中甲醛检测的实验室内部质量控制措施。方法:用电子时控大气采样器DDy-1.5采集气体后按公共场所中甲醛测定方法 GB/T18204.26-2000中酚试剂分光光度计法进行检测分析。结果:通过采样环节、实验室仪器使用环节、实验室检测分析等过程有效实施质量控制,将样品测定的精密度和准确度结果均位于均值-减差控制图和回收率控制图的上下控制限之间,有效地将甲醛测定结果可控制在允许的置信水平内。Objective： To study the indoor air formaldehyde detection method of the laboratory internal quality control. Measures： When charged with electricity atmospheric sampler DDy to 1.5 after collecting the determination method of formaldehyde in public places in the GB/T18204.26-2000 phenol reagent spectrophotometer method for testing analysis. Results： Through the sample link, laboratory instruments use link, effective implementation of the quality control of laboratory testing analysis process, the accuracy and precision of the sample determination results are located in poor control chart and average recovery between the upper and lower control limit of control chart, will effectively formaldehyde determination results can be controlled within the allowed the confidence level.
