Techniques & Tools

David Duffy, Ulf Landegren, Antoine van Oijen, and Menno Prins crash through the concentration barrier and investigate the ultimate limit of analytical sensitivity.

I find myself attempting a graceful “glissando” into greying semi-retirement. And what better way (other than Volvo-driving) to add gravitas and prestige than by teaching?

As associate scientific director of Nutritional Chemistry and Food Safety at Covance Laboratories, Katerina Mastovska must tackle the most challenging analytical questions. And she loves every second.

As new technology platforms push us to the limits of what’s possible, the metabolomics community is closing in on the future of the field: routine and rapid quantitative analysis.

Way back in the mid-1960s, somewhere in the North American Midwest, J. Calvin Giddings spent a sleepless night in a noisy motel room. Even the room’s rattling air-conditioning unit gave him a hard time.

Christoph Johann, founder and MD of Wyatt Technology Europe, the company that originally introduced field-flow fractionation (FFF) instrumentation to Europe’s analytical scientists, looks at the history of the technique and shares his involvement with the field.

Comprehensive two-dimensional gas chromatography (GC×GC) is a step up from standard GC and involves connecting two distinct columns each possessing stationary phases with different selectivities to achieve high resolving power.

For most of my industrial career, I’ve been a modeler and have had to deliver practical results.

Recently, a vacuum ultraviolet (VUV) detector for gas chromatography (GC) was introduced into the market, taking a top five spot in The Analytical Scientist Innovation Awards 2014 in the process.

My group is working on several new things for GC×GC right now.
