In modern time,some people considered it as a bone of 'Instrumental Analysis'; a very similar term.Analytical chemistry has its very practical application.Like biomedical applications,quality control of industrial manufacturing ,environmental monitoring,and especially forensic science.
Methods of Detecting analytes
1. physical means
* mass * color * refractive index * thermal conductivity
2. with electromagnetic radiation (Spectroscopy)
* absorption * emission * scattering
3. by an electric charge
* electrochemistry * mass spectrometry
