Abstract A quantitative measurement method for fine particle bisulfate in ammonium bisulfate collected from the ambient air onto Teflon filters is described. Infrared absorbance measurements of the Teflon filters are made before and after particle collection. Subtraction of the two spectra reveals the absorbance spectrum of the particles. This method provides a specific, nondestructive, direct measurement of ammonium bisulfate. As such, the method has distinct advantages over indirect methods involving ion balance in solution.
