Three Wizards of Sample Preparation

At Riva 2014 (the 38th ISCC and 11th GCxGC Symposium), Pat Sandra stood on the stage periodically shaking an imaginary separation funnel – much to the amusement of the audience. “I find it just incredible to see what people are doing in application notes,” Sandra remarked. “They have the very best instrumentation, for example to determine the composition of drinking water at the sub-parts per trillion level with triple quadrupole mass specs and gas chromatography. But do you know what their sample preparation is? They take one liter of water, add 100 ml of dichloromethane, shake it for half and hour. Then they put the dichloromethane in a vial, evaporate it down to 0.5 ml – don’t worry, it’s just going into the air –  and then they inject. We need to do something about that…”

About the Author

Rich Whitworth

Rich Whitworth completed his studies in medical biochemistry at the University of Leicester, UK, in 1998. To cut a long story short, he escaped to Tokyo to spend five years working for the largest English language publisher in Japan. "Carving out a career in the megalopolis that is Tokyo changed my outlook forever. When seeing life through such a kaleidoscopic lens, it's hard not to get truly caught up in the moment." On returning to the UK, after a few false starts with grey, corporate publishers, Rich was snapped up by Texere Publishing, where he spearheaded the editorial development of The Analytical Scientist. "I feel honored to be part of the close-knit team that forged The Analytical Scientist – we've created a very fresh and forward-thinking publication." Rich is now also Content Director of Texere Publishing, the company behind The Analytical Scientist.
