Techniques & Tools Mass Spectrometry

In the FFF Hot Seat

| Christoph Johann

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.


Fields & Applications Proteomics

The Rise, Fall and Rise of FFF

| Wim Kok

Nearly half a century ago, J. Calvin Giddings published a letter that laid out his ideas for a new separation strategy. It resulted in a collection of techniques known as field-flow fractionation (FFF)


Techniques & Tools Data Analysis

Taking FFF to the Next Dimension

| Thorsten Klein

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.


Techniques & Tools Gas Chromatography

Young Guns: Ionic Liquids for GCxGC

| Jared Anderson

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.


Fields & Applications Forensics

Forensic Science Under Fire

| Jose Almirall

Hair analysis has been spectacularly debunked as “pseudoscience” – what now?


Techniques & Tools Mass Spectrometry

Rodeo Champ

| Mark Schure

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


Fields & Applications Metabolomics & Lipidomics

Metabolomics: the Superglue of Omics

| Martin Giera, Mary E. Spilker, Gary Siuzdak

As the profile of metabolomics soars, some thoughts on the future of the field


Techniques & Tools Mass Spectrometry

Vacuum-UV Lone Star versus MS

| Kevin Schug

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.


Techniques & Tools Mass Spectrometry

Wrangling Orthogonality in Multidimensional Chromatography

| Michelle Camenzuli

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


Techniques & Tools Gas Chromatography

Reigning in Multidimensional Data

| James Harynuk

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