Steady State and Lifetime Nanotechnology EEM Spectrofluorometer
The Nanolog® series of spectrofluorometers are specifically designed for research in nanotechnology and the frontiers of nanomaterials. A complete spectrum can be scanned as fast as a few milliseconds, and a full excitation emission matrix scan can be taken in just seconds.
Based on the world-wide proven technology of the Fluorolog®, the Nanolog detects fluorescence in the near-IR from 800 to 1700 nm (optional multi-channel detection to 2 µm, single-channel detection to 3 µm), with visible and UV options possible. With the Nanolog comes specially designed software called Nanosizer, ideal for classifying SWNTs, Quantum Dots and performing energy transfer calculations. Saving custom experimental routines and instrument layouts has never been easier.
Nanosizer® - for Single‐Walled Carbon Nanotube Excitation‐Emission Map Simulation and Analysis
Nanosizer® in Origin® Pro 8 simplifies the process for simulation and analysis for single‐walled carbon nanotube excitation‐emission map simulation and analysis. Nanosizer is used with our Nanolog spectrofluorometers, which are specifically designed for research in nanotechnology and nanomaterials. Nanosizer comes with our patented double-convolution-integral algorithm specially designed for determining chirality and diameter of single-walled carbon nanotubes.
Nanosizer® lets you simulate excitation-emission maps of SWNT near-IR fluorescence to compare to your actual data. Using built-in or custom libraries, Nanosizer® rapidly assigns specific peaks to particular SWNT (n,m) structures, and even generates helical maps. Nanosizer® also greatly simplifies FRET studies of SWNT bundles, length-distribution analyses, and nanotube purification analyses. Nanosizer®even offers a platform suitable to support future ISO and ASTM standards for identification and purification of semiconducting SWNTs.
