Mass Spectrometry

When Richard Fussell still worked at the UK’s Food and Environment Research Agency, he was the first customer to see the Thermo Scientific Q Exactive™ GC in action – well ahead of its official launch at ASMS 2015. The latest Orbitrap™ innovation made him wonder – not for the first time – if the grass was greener on the other side.

Coupling gas chromatography with Orbitrap™ technology wasn’t easy, but the outcome – the introduction of the Thermo Scientific Q Exactive™ GC – represents a big step towards bringing full-scan, high-resolution, and accurate mass data into routine labs around the world. And my dream of an “Orbitrap in every lab” inches ever closer.

Research into migration of packaging materials into food began decades ago. And despite the relatively inconspicuous nature of this niche area, it is characterized by some of the most significant modern-day challenges in food analysis.

Sitting Down With…Robert (Bob) Kennedy, Distinguished Professor and Chair of Chemistry at the University of Michigan, Ann Arbor, USA, and Chair of the forthcoming HPLC 2016 conference in San Francisco.

The gift of analytical capability is welcomed with open arms, but needs to go beyond core instrumentation.

High-precision isotopic analysis of essential metals is beginning to show real promise for medical diagnoses. Here, I share some of the progress in this exciting application area.

The molecular weight, molecular weight distribution and size of three common polymers are measured using OMNISEC. This information can provide insight into the physical properties and behavior of these synthetic polymers.

As fraudsters become increasingly knowledgeable and adept, authentication of food and beverages becomes more and more challenging. I was keen to see if GC-Orbitrap technology represented a new tool in the defense of food safety and quality – and Scotland’s centuries-old whisky industry.
