A Level Playing Field?

| Rich Whitworth

Last year, we berated ourselves for the disappointing show of women in our Top 100 Power List (a measly eight percent). So, how did we do in our Top 40 Under 40?

Could a new acoustic micropump inspired by the legs of swimmers open doors for microfluidics?

Fields & Applications Preparative/Process Chromatography

The Art of Analysis, Reprised

| Anne Francois Aubry

“During human progress, every science is evolved out of its corresponding art,” wrote Herbert Spencer in 1861. So, is analytical chemistry truly as much an art form as a science?

Techniques & Tools Technology

Recognizing Research in Industry

| Martin Gilar

There are more researchers working in industry than in academic facilities – and, in many ways, they are shaping the future more profoundly than their academic colleagues. It’s time to push them into the limelight.

Late to the Flipping Party

| Olaf de Groot

Christopher Harrison described the flipped classroom as an inevitable evolution in teaching. And he’s right – but why has it taken so long for university lecturers to catch on?

Techniques & Tools Food, Beverage & Agriculture

A Recipe for Disaster?

| Bert Pöpping

Incorrect labeling of foods – sometimes a result of inappropriate or incorrect analysis – can cause needless suffering for people with food allergies. We analytical scientists must step up and change the landscape of food allergen analysis.

Techniques & Tools Data Analysis

Why We Need the Theory of Sampling

| Kim H. Esbensen, Claas Wagner

Without representative sampling, measurement uncertainty is compromised. Here, we present the current Theory of Sampling versus Measurement Uncertainty debate.

Our Unholy Alliance

| Lee DesRosiers

Science and business: tenacious partners in a shaky marriage or eternally bound nonidentical twins?

Techniques & Tools Technology

The ‘Noble’ Undertaking of Helium Conservation

| Ed McCauley

Is it possible for a cylinder of helium to last years, rather than months? When using a novel split-splitless injection port for gas chromatographs, the simple answer is “yes.” Here, I present the more technical answer.

Fields & Applications Sample Preparation

Transforming a black art: adding rheometry to the formulation toolkit

Rheology is the science of material flow. It is also a science with a reputation for some fairly daunting mathematics. But look past these first principles and rheology has immediate relevance in formulation which is readily appreciated and easily exploited.

Fields & Applications Technology

Characterization of Protein-Protein Interactions using triple detection size exclusion chromatography (SEC-TD)

Work performed in conjunction with the Institut Pasteur, Paris, France.In this application note, triple detection size exclusion chromatography (SEC-TD) is used to understand the ability of proteins to form ordered, structured complexes. The controlling mechanism behind these protein complexes is fundamental to our knowledge of protein signaling pathways and the physiological responses they control.

Techniques & Tools Sample Preparation

GPC Characterization of Nylon using Formic Acid for Reduced Cost per Analysis

| Sponsored by Malvern Panalytical

GPC/SEC can be used to characterize commodity or bulk manufactured polymers. Here we describe how the use of formic acid instead of hexafluoroisopropanol (HFIP) as the dissolution solvent and/or mobile phase can lead to improvements in both cost per analysis and health and safety.
