摘要

The objective of this project was to perform an interlaboratory comparison of methods recently developed for the measurement of formaldehyde and other aldehydes in ambient air. The methods under study include the chemiluminescence (CL) method for formaldehyde developed at Harvey Mudd College, and the derivatization - high pressure liquid chromatography method (HPLC) developed at Environmental Research and Technology, Inc. for formaldehyde, acetaldehyde, and other aliphatic and aromatic carbonyls. In the case of formaldehyde, the results obtained using these two methods were also compared to those obtained using the chromotropic acid method (CA) and the long-path Fourier transform infrared spectroscopy method (FTIR) developed and employed by Dr. P. Hanst of the US Environmental Protection Agency. The project was carried out according to three phases involving side-by-side measurements of aldehydes in standard and ambient air samples.
