Green chromatography techniques

It is crucial demand of recent times to make the industrial productions eco-friendly as much as possible which not only promotes sustainable development but also lowers the financial burden by increasing yield with cost-effective approaches. Hence, the interest has leaned toward the use of green downstream processing for industrial products precisely reflecting from increased number of publications on green analytical techniques. As the research on organic compounds production makes use of chromatographic techniques to analyze different components, the extensive efforts have been performed to make chromatography techniques green which can potentially be possible at each step right from preparation of sample to analytical identification. 

Usually, gas chromatography can be greener with low energy consumption whereas liquid chromatography with lesser solvents usage. This chapter depicts various green techniques used in gas and liquid chromatography, for instance, manipulating the process parameters like analyte preparation, chromatography type, stationary phase, mobile phase, column size, and temperature. In addition to discussing various aspects of green chemistry, there is substantial discussion about assessment of green techniques using various mathematical and statistical approaches. Finally, the advanced research approaches are recommended to explore the potential and overcome the challenges for the commercialization of green chromatographic techniques.
