This application note presents how and if NIR spectroscopy can be used to identify optimal and sub-optimal lots of powdered gelatine agar.

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.
