GC to identify organic molecules

I don't know what you are getting at with "It was in the 1940s, however, that there was a great revolution in gas chromatography (GC). Although GC was a wonderful technique for analyzing inorganic compounds, less than 20% of organic molecules are able to be separated using this technique." GC did not exist until James and Martin (1952) (in those days we called it gas liquid chromatography or GLC); and GC was never a technique for measuring inorganic compounds. Your 20% of organic molecules is probably about right or an overestimate (my guess is more like 10%) because the molecule has to be (a) reasonably volatile and (b) to some extent soluble in the organic stationary phase.
