Application

Ammonium sulfate may be used in methyl cellulose precipitable tannin assay to examine wine tannin in finished wine samples. It may also be used in making externally mixed aerosols for analyzing the 1 × 3 tandem differential mobility analyzer (1 × 3-TDMA), which is mainly employed for determining the irreversibility of the hygroscopic growth factor of aerosol particles.
