The NS2 NanoSpectralyzer®

NS2 is the world's only three-in-one spectrometer for carbon nanotubes. The NS2 provides all of model NS1’s state-of-the-art capabilities for analyzing SWCNT samples through near-IR fluorescence and absorption. In addition, the NS2 captures Raman spectra of all CNTs, whether single-walled, multi-walled aggregated, large diameter, or chemically altered. All spectra are automatically measured with a single placement of the sample cuvette. Sophisticated software then performs integrated data analysis to characterize the CNT sample.
