Chemical Analysis
Chemical analysis provides important information for science and industry.
Chemical analysis is used: To test samples of air, soil and water to identify
pollutants To help in the diagnosis of disease In quality control tests of food, drug and other
industries
Different methods of qualitative analysis are suited to each of these different applications. The techniques are designed to test a sample of a substance for the properties of a particular element or compound.
Techniques of Qualitative Analysis
Some techniques include: chromatography emission and absorption spectroscopy solubility of ions characteristic properties and reactions
of substances
