Purpose This paper will discuss indoor formaldehyde AHMT spectrophotometry routine laboratory test and inter-laboratory analytical quality control. Method Formaldehyde, collected by solid phase adsorption tube and eluted with eluent, analysis by AHMT spectrophotometry of Formaldehyde in air of residential areas health inspection standard method(GB/T16129-1995). Result The results of precision and accuracy are between the upper and lower control limits of the mean-range charts and recovery control charts. The difference between uniform standard solution and the laboratory standard solution is less than 5%. Conclusion Through the implementation of laboratory analytical quality control procedures, we can understand the process of measuring the degree of error sources and take appropriate measures to correct measurement results controlled within the allowable level of confidence.
