I have a set of data with 10 variables. The first variable is categorical and/or ordinal. I am not 100% sure because my data are categorised into 4 groups (i.e. C, Y, A, R). C, Y, A, R represents “less than 5%”, “5%-9.99%”, “10%-14.99%” and “15% & above” respectively.

Chromatography

Chromatography

Traditionally in chromatography the eluting solvent is an organic compound, such as hexane or acetonitrile. Explain, in terms of green chemistry, why this experiment uses environmentally friendly compounds, such as table salt, water and isopropyl alcohol. Research an alternative solvent that is currently being used in chromatography to reduce costly wastes and describe the benefits of that solvent, as well as any complications that may be related to the use of the alternative solvent. Your answer must be clear and complete (with references)
