Features

The light source is a highly stabilised Xenon arc lamp with an optical stability better than 0.1% with an auto-start facility in instrument power ON.

The excitation and emission monochromators are designed for high optical throughput and each has a triple grating turret for flexible choice of gratings. This allows the instrument to be optimised for several spectral ranges depending upon customer requirements. Each monochromator is also fitted with continuously variable bilateral knife edge slits allowing spectral pass band from 0.1nm to 10mm.

FluoroSENS is fitted with several key spectroscopy features as standard. These include a reference photodiode detector for corrected excitation spectra, corrected emission channel, integrated order sorting filter wheel and filters as well as an optical attenuator to allow signal optimisation.

As standard the large sample chamber is designed with high light gathering optics to utilise as much of the sample signal as possible. AS standard the fluoroSENS comes with a singel cuvette holder on a positioning stage to ensure sample and signal optimisation. Optional samples holders include for example: temperature controlled options, four cell motorised turret, front face sample holder for solid or power samples, magnetic stirrer, optical fibre adapters and a motorised 96 well plate reader.

Each fluoroSENS uses a single photon sensitive photomultiplier detector. This detector can be exchanged for different spectral ranges to ensure complete optimisation to customer needs. Optional NIR detectors are also available.

The fluoroSENS uses a new class leading data acquisition system that provides all signal collection in the one board. This includes a 100M counts per second photon counting module as well as low noise 16 bit analogue-to-digital detectors for sample temperature sensing and the reference detectors.

Uniquely, fluoroSENS offers a transmission detector as a sample chamber option to allow the measurement of sample transmission simultaneously with the fluorescence emission or excitation measurements. This allows the user to directly monitor sample photo-bleaching or aggregation etc that might otherwise invalidate the fluorescence measurement.

The system software contains all of the control, data collection, and analysis functions to make high quality fluorescence measurements. It has the option to save all experimental parameters and to define a quick load measurement function. This function permits routine measurements to be set-up and stored for repeat use. Full flexibility is offered to edit these functions.

Spectral functions provided as standard include:

• Exc, Em, and Synchronous Spectra
• Anisotropy
• Ex-Em Mapping, Synchronous Mapping Spectra
• 2D, 3D, and contour plotting
• Spectral Arithmetic, Normalisation, Smoothing, Differentiation, Integration, Spectral Conversion, Anisotropy Analysis (incl. G-factor correction), etc
• Comprehensive export facilities for the data and the graphical

The fluoroSENS also has a flexible range of upgrade paths, including:

• Pulsed Xe lamp for phosphorescence spectra and lifetimes
• Silicon photo-diode transmission detector
• Low temperature sample options including nitrogen and helium cryostats
• Stop-flow accessory
• Optical fibres for remote sensing applications
• 96 well plate reader accessory
