Spectroscopy Applications

A method for the direct analysis of trace elements in seawater samples by ICP-MS, one of the most difficult matrices to analyse for the presence of heavy metals and other trace elements.

The different steps involved in analysing microplastics—including the initial sampling through to data analysis—are discussed in this article.

This article shows how an ultra-stable femtosecond amplifier enables high data output in 2D IR spectroscopic studies of biological membranes and surfactants.

Plot of identified SWCNT structures from the excitation emission matrix

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.
