The Use of Ammonium Acetate as an Ion
01.03.1989Ammonium acetate is the most generally applicable material with reversed-phase solvent systems. The requirements of thermospray operation (i.e., addition of a volatile salt and use of aqueous based solvent systems) impose certain limitations on the modes of LC available to ensure compatibility with the combined technique.

Soil Nitrate And Extractable Ammonium By Flow Injection
Summary. This method involves the extraction of nitrate (NO 3 -N) and ammonium (NH 4 -N) from soils using an equilibrium extraction with 2.0 N KCl solution. Nitrate is determined by reduction to nitrite via a copperized cadmium column. The nitrite is then determined by diazotizing with sulfanilamide followed by coupling with N- (1-naphthyl

How do ammonium sulfate and gypsum differ?
With 24 units of sulfate sulfur and 21 units of ammonium nitrogen, Sulf-N ammonium sulfate is a high-analysis fertilizer offering 45 units of essential plant nutrition in every 100 pounds of product. Gypsum, by contrast, contains only 17 units of sulfate sulfur. The rest of the nutrient analysis – 22 percent – is calcium.
