Raman and XRF microscopies are used to study meteorites.
Fluorescence spectroscopy, Raman microscopy and particle size distribution analysis are used to characterise sunscreens.
This application note presents how and if NIR spectroscopy can be used to identify optimal and sub-optimal lots of powdered gelatine agar.
Single-wall carbon nanotubes (SWCNTs) have unique electrical, thermal, mechanical and optical properties which make them attractive for a wide variety of applications; ranging from drug delivery to battery electrodes. SWCNTs can be envisaged as a graphene layer that has been rolled up into a cylinder with different tube structures possible depending on how the graphene layer is rolled. The tube diameter and chirality (orientation of the graphene lattice with respect to the tube axis) are defined by the roll-up vector.
EDXRF instrumentation is ideal for determining concentrations of multiple elements on air filters in compliance with US EPA requirements.
The thermal reaction of IPA on CeO2 catalysts has been investigated over a range of temperatures using the Selector™ Environmental Chamber accessory.
This application note shows how to characterise protein therapeutic formulations for aggregation behaviour in a matter of seconds with A-TEEM spectroscopy.
Analysis of heavy metals and toxic elements as traces in aqueous solutions demands high sensitivity and accuracy of measurement.
