Chemical profiles link production methods with characteristic flavors

This paper shows how using a solvent trap can be used to prevent sample drying/solvent loss during extended testing, helping to ensure that only rheological changes are being measured and not artifacts resulting from drying of the sample at the air/sample interface.

What drives someone to throw aside selfish pursuits to focus on projects with true philanthropic impact? Here, the winners of the 2015 Humanity in Science Award provide their answers.

In this application note, we'll describe the successful molecular weight measurement of a polystyrene, PMMA and PVC sample using the OMNISEC system. This instrument can accurately measure the absolute molecular weight of any polymers independent of elution volume or structure. Although the measurements here have been performed using simple polymers, these methods can be applied to any polymer measured by GPC.

You know the meat that’s been sitting in your fridge for a while... is it still safe?

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

As associate scientific director of Nutritional Chemistry and Food Safety at Covance Laboratories, Katerina Mastovska must tackle the most challenging analytical questions. And she loves every second.

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

When bottles of beer from the 1840s were found on a shipwreck, there was only one thought on the minds of analytical scientists: what chemicals do they contain?

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.
