Hello fellow Wikipedians,

I have just added archive links to 1 one external link on Monolithic HPLC column. Please take a moment to review my edit. If necessary, add after the link to keep me from modifying it. Alternatively, you can add to keep me off the page altogether. I made the following changes:
 * Added archive https://web.archive.org/20090204080923/http://www.laboratoryequipmentworld.com:80/hpcl-market.html to http://www.laboratoryequipmentworld.com/hpcl-market.html

When you have finished reviewing my changes, please set the checked parameter below to true to let others know.

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.
