Formulating the 12 principles of Green Analytical Chemistry (GAC), by modification of the Green principles made them more applicable towards Analytical chemistry. These principles hold importance in designing of new methods or instruments. The focus of greening a chemical method is by generating solvent-less techniques or using alternative solvents like ionic liquids. Miniaturization of separation techniques employing FAC instruments would be another approach to reduce solvent consumption and production of analytical wastes. Capillary electrophoresis was rather unknown for its use as an alternative in place of GC, until recently. Owing its wide application and use, greening chromatographic methods like HPLC, GC is the upcoming trend. Various newer techniques complying with the principles of GAC are a safer option over conventional non-green methods for analysis. The article is primarily an overview covering the introduction and development of green methods in analytical chemistry.
