Why GPS-SEC is the Only Light Scattering Technique for Molecular Weight Determination

A newly available application note from Malvern Panalytical explains why, when measuring samples using Gel Permeation Chromatography/Size Exclusion Chromatography (GPC/SEC), low angle light scattering (LALS) is the only LS technique that actually measures a scattered light intensity directly proportional to molecular weight.

Measuring Nanoscale Structures Using Tiny Rulers

With the advent of nanometer-sized machines, there is considerable demand for stable, precise tools to measure absolute distances and distance changes. One way to do this is with a plasmon ruler. In physics jargon, a "plasmon" is the quasiparticle resulting from the quantization of plasma oscillation; it's essentially the collective oscillations of the free electron gas at a metallic surface, often at optical frequencies.

Microminiaturized Device That Can Make Complex Viscosity Measurements

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a microminiaturized device that can make complex viscosity measurements—critical data for a wide variety of fields dealing with things that have to flow—on sample sizes as small as a few nanoliters.
