[Evaluation on the performance of formaldehyde analyzer with standard formaldehyde gas generated by diffusion tube].
The performance of portable formaldehyde analyzer was tested by a standard formaldehyde gas generation system, the gas was generated by diffusion tube. The evaluation included testing the zero, calibrating the drift, response times and the accuracy of the analyzer, and testing the effect of relative humidity. In compare with the standard method (AHMT method GB/T16129) testing in the fields, the overall relative uncertainty of the formaldehyde analyzer was 7%.
