Analytical chemistry is concerned with the chemical characterization of matter and Everything is niade of chemicals. the answer to two important questions: what is it (qualitative) and how much is it Analytical chemists determine what (quantitative).
Chemicals make up everything we use or consume, and knowledge wd how much. of the chemical composition of many substances is important in our daily lives, Analytical chemistry plays an important role in nearly all aspects of chemistry. For example, agricultural, clinical. environmental, forensic, manufacturing. metallurgical, and pharmaceutical chemistry. The nitrogen content of a fertilizer determines its value. Foods must be analyzed for contaminants (eg., pesticide residues) and for essential nutrients (e.g., vitamin content). The air in cities must be analyzed for carbon monoxide. Blood glucose must be monitored in diabetics (and, in fact, most diseases are diagnosed by chemical analysis).
The presence of trace elements from gun powder on a murder defendants hand will prove a gun was fired. The quality of manufactured products often depends on proper chemical proportions. and mea-surement of the constituents is a necessary part of quality control. The carbon content of steel will determine its quality. The purity of drugs will determine their efficacy,
