Mass Spectrometry

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.

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.

The quest for greater separation power, in terms of peak capacity, has inevitably led to the development of multidimensional chromatographic techniques.

For years, thin layer chromatography has been working hard in the background, the choice technique in certain applications. More recently, hyphenation with mass spectrometry has been a relatively quiet – but very real – game-changer. What have you been missing?

In 2014, Select-eV took a top spot in The Analytical Scientist Innovation Awards (TASIAs). Here, the technology is teamed up with (GC×GC)-MS in an unusual international environmental monitoring project.

When I was asked to evaluate a brand-new instrument with disruptive potential in my field, I did not spend long thinking about the answer. Here, I share a little background and my first impressions.

Can wooden toothpicks be the key to improving detection of drugs of abuse using mass spectrometry?
