At Applied NanoFluorescence (www.appliednano.com), we manufacture cutting edge spectrometers for analysis of nanomaterials such as carbon nanotubes or quantum dots. Our products include the NS1, the NS2 and the NS3 NanoSpectralyzers, and the new compact NS MiniTracer. The most versatile of these instruments is the NS3, a customizable and modular NanoSpectralyzer. In addition to its core function as a sensitive near-infrared fluorometer and absorption spectrometer, the NS3 can be configured with any of the following spectral capabilities: visible emission, extended NIR emission, UV absorption, visible absorption, extended NIR absorption, and Raman. The NS1, NS2, and NS3 all include sophisticated software that can rapidly estimate the (n,m) distribution of semiconducting single-walled carbon nanotubes.
