Instrumentation and method of analysis are a study of chemistry that involves analyzing the components of substances, both qualitative and quantitative analysis, using modern instruments. These instruments examine the physical and chemical properties of the substances of interest and convert them into concentration. For example, the use of spectroscopy techniques for trace analysis, the development of modified electrodes for specifically targeted analysis, the separation of different groups of substances using chromatographic methods, the use of automated flow analysis techniques, and the development of test kits for various important substances. The method of analysis utilizes both standard and newly developed methods and can be applied to various types of samples such as food, environment, agriculture, clinics, and forensic science. Additionally, analytical services can also be obtained from external agencies.
