All-reflective optics Nanolog fluorescence spectrometer for perfect focus at all wavelengths from the UV to NIR
Note: The Sensitivity Specification listed below is the same with either the 450 W xenon or the 75 W xenon due to the enhanced collection efficiency of the PowerArc!
monochromator configuration (the 360 mm focal length double monochromator is recommended for the highest stray-light rejection and sensitivity).
Note:Specifications hereare basedon 180mm monochromator withstandard 1200grooves/mm gratingblazed at 330nm. Othergratings areavailable.
Resolution: 0.2 nm
0–1300 nm mechanical range; throughput based on grating’s blaze
Set automatically (0–30 nm single-grating, 0–15 nm double-grating)
All reflective optics sample compartment with single cuvette sample compartment tray for quick replacement with variety of optional sample hold- ers. Reference photodiode for excitation correction from 240–1000 nm. Optional front-face detection for highly turbid samples in solution. Optional T-Format detection to allow optional second emission-detection channel.
Emission Imaging Spectrograph
iHR320, for multi-channel acquisition, with triple-grating turret. Can be configured with one or two exit ports each for multi-channel or single channel detectors. Equipped with 150 grooves/mm grating for multi-channel detection of entire emission spectra with a single acquisition.
0–1500 nm mechanical range (using a 1200 grooves/mm grating and single channel detector)
Choice of up to two of the following:
Optional T-Side Emission Monochromator for Single Channel Detectors
Specifications are the same as excitation monochromator above1
Single Channel Detectors
Windows™-based FluorEssence™ software supplies all scanning, time-based, and accessory data acquisition plus complete control of all hardware, plus Nanosizer™ for fitting of single-walled carbon nanotube spectra to known library to determine chiralities and diameters.
Water Raman Signal-to-Noise Ratio of 15,000:1 (FSD method), 350 nm excitation, 5 nm bandpass, 1 second integration, no filters or averaging, with R928P photomultiplier tube.
The Nanolog 3-22-iHR, pictured here, is configured with a double-grating excitation and emission monochromator, plus an imaging spectrograph for a second emission channel.
Schematic shows a highly versatile Nanolog equipped with a 450 watt xenon lamp housing, double excitation monochromator for ultimate stray light rejection, T-Format sample compartment with multichannel iHR320 imaging spectrograph equipped with a Symphony NIR InGaAs array detector and a T-Side double emission monochromator with a PMT detector for ultimate sensitivity and stray light rejection.
