Fields & Applications

Sitting Down With... Richard Pollard, President of Ocean Optics, Dunedin, Florida, USA.

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)

Ahead of ISCC & GC×GC 2015 symposium, we bring together a posse of multidimensional ranchers for a glimpse of what’s going on in the field – and what to expect at the Texan conference.

Even as advances in engineering technologies and manufacturing processes have lowered the cost to make and distribute products, the demand for continued improvement is as strong as ever.

Copolymer analysis can be complex. The 2D approach is the only way to determine molar mass and chemical composition distributions simultaneously.

Consider designing the readout first when developing point-of-need assays.

The ageless wisdom, “imitation is the sheerest form of flattery,” once again holds true. Unfortunately in quantitative analysis, imitation comes with real consequences.

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

In some industries, for example, in early-stage pharmaceutical development, it is desirable to measure particle size from a small samples of dry powders. However measuring small quantities risks measuring a sample that is not representative of the bulk material. In this application note, we demonstrate the capability of the Aero S dry dispersion unit and the Mastersizer 3000 to measure small quantities of pharmaceutical materials dosed with large particles and to detect those large, anomalous particles.

More than 15,000 UK school students have been given the opportunity to learn about spectroscopy through hands-on experience thanks to The Royal Society of Chemistry’s Spectroscopy in a Suitcase (SIAS) scheme.
