Importance

Chemical analysis is an important branch of chemistry that plays an important role in the progress of science and in many fields:

• Medicine: diagnosis depends on measuring sugar, albumin, urea and cholesterol; it makes the doctor's diagnosis and treatment easier, and it gives the amount of active ingredient in medicines.
• Agriculture: analysing soil (acidity or basicity, kinds and percentages of elements) tells which fertilizers to add and how to improve soil and crops.
• Industry: ores and products are analysed to check identity and compliance with standard specifications.
• Environment: e.g. measuring nitrogen oxides in air and pollutants in water. There are countless other examples based on studying the chemical composition of substances.
