The micro-analytical process is the identification and quantitative components for analysis. In this case, the surface is the analyze is less than 1 cm2.
This process is applied in the modem spectroscopy, UV, IL NMR, X-Ray, Mass spectrum etc. Again in chromatography, HPLC, GPLC, X-Ray diffraction, electrophoresis, the microanalytical process is followed. Since the amount of analyte is very small, the amount of produced wastage is very small so that the environment remains clean.
