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.

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.
