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. 

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.

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.

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?

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.

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

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.

We started The Analytical Scientist with a bold, three-word mission: recording, scrutinizing, celebrating.

The Analytical Scientist Innovation Awards (TASIAs) return for 2014 to showcase new technologies, instruments and software solutions that are out of this world
