About This Instrument

It is used to determine nitrogen in Soil, inorganic and organic fertilizer and Protein Content of plant samples. The method consists essentially of transforming all nitrogen in a weighed sample into ammonium sulfate by digestion with sulfuric acid, alkalizing the solution, and determining the resulting ammonia by distilling it into a measured volume of standard acid, the excess of which is determined by titration.

Sub Category	Food and beverage, Water, Pharmaceuticals
Testing Parameters	Concentration of Individual elements in ppm and ppb level
Description	Atomic absorption spectrometry (AAS) is used primarily to determine the concentrations of individual elements in solution. As such, AAS is used in food and beverage, water, clinical research, and pharmaceutical analysis. It is also used in mining operations to determine, metal concentration.
