NanoSpectralyzer NS1 Dec 19, 2007

The NanoSpectralyzer® (patent pending) is a unique, easy-to-use spectrometric instrument that is custom-designed to give detailed compositional analyses of single-walled carbon nanotube (SWNT) samples in aqueous suspension. It consists of a compact optical system plus specialized software for apparatus control, data analysis, and results presentation. This system analyzes samples in seconds using the most advanced research findings in nanotube spectroscopy. It can be used in automatic mode for routine analyses or with full manual control for sophisticated research projects.

Each semiconducting species of SWNT has a characteristic and known near-infrared fluorescence frequency. This instrument uses selected excitation wavelengths and a multichannel detector array to quickly capture a sample’s emission spectrum with high sensitivity and precision. The measured spectrum is then automatically analyzed to reveal the specific underlying components and provide an (n,m) inventory of semiconducting SWNT species in the sample. Relative apparent concentrations of these species are deduced and displayed in tables, as graphene sheet maps, and as diameter histograms. Up to ten spectra per second can be measured for kinetic studies or eluent monitoring. The NanoSpectralyzer is also a rapid near-IR absorption spectrometer. It compares the strengths of absorption and emission features to quantify a sample’s dispersion quality and nanotube perfection.

Who should use the NanoSpectralyzer?
1)Nanotube researchers (To measure SWNT sample compositions; To develop methods for sorting SWNTs by structure; To sensitively detect SWNTs in biological samples; To study structure-dependent kinetic processes)
2)Nanotube producers (To monitor consistency of production runs; To adjust process conditions and control product compositions)
3) Commerical nanotube users (To characterize and qualify incoming SWNT material; To assess quality of SWNT dispersions)
