Sciencetech Fluorescence Spectroscopy
Overview
Fluorescence Spectroscopy is a powerful analytical technique with applications in biology, biochemistry, physics, chemistry and medicine. The upgradable capacity of Sciencetech Fluorometer systems provide the customer with the opportunity to begin with a low-end options and improve the system as requirements and funds increase.
Sciencetech Fluorometer Systems
Sciencetech currently offers two Steady State Fluorometer systems, models 7336 and 7556. Model 7336 is available only as a steady-state system. Model 7556 has upgrade options that include T-configurations, infrared detectors and florescence lifetime measurements in milliseconds, microseconds and nanoseconds. The standard Sciencetech Steady State Fluorometer system includes a light source, excitation monochromator, sample chamber, emission monochromator and detector.
Model 7336 uses the Sciencetech 9030 100 mm monochromator for both the excitation and emission monochromator components. The 9030 is a compact monochromator with a single concave holographic grating. Model 7556 uses Sciencetech’s 9055, quarter meter monochromator for both the excitation and emission monochromator components. The 9055 is a high resolution instrument with a triple grating turret and automatic grating switching.
Light sources for Steady State Fluorometer systems are Xenon arc lamp systems. The 7336 and 7556 both use the SC3201 transmission/ fluorescence sample chamber and a photomultiplier detector system including photomultiplier housing with power supply and photomultiplier tube. A thermoelectric cooled PMT housing with temperature controller is also available.
Model 7556 includes a Reference UV-enhanced Silicon PIN fast photodiode for synchronization when pulsed sources are used. This component is offered as an option to the 7336. Both models include all coupling optics required for source, monochromators, sample chamber and detector. Data acquisition board and system control software are included with both systems. Other accessories and options such as optical breadboards and filter wheels are also available.
Fluorescence Spectroscopy Basic System Consists of:
This couples the source to excitation monochromator. The Xe lamp is connected to one of the inputs. The other two are for attachment of flash lamps or other desired wide band sources. Quartz optics.
Our model 9030 is a compact 100 mm monochromator of Seya-Namioka type with a single concave holographic grating. Aperture is f/3.2 and the model comes with one set of fixed width slits.
For Model 7556:
Our model 9055 direct drive monochromator is a Czerny-Turner type with an asymmetrical optical system. The triple grating turret is controlled by a computer through a RS232 serial port. Turret minimum step angle with 400 step/rev motor, is 0.0032o in half-step mode and 0.00064o in microstep mode. Concave mirror focal lengths are 200 mm input and 250 mm output. Input aperture is f/3.5. Slits have bilaterally adjustable width with micrometer control and adjustable height. Two slits are included with each monochromator.
This couples the source to excitation monochromator. The Xe lamp is connected to one of the inputs. The other two are for attachment of flash lamps or other desired wide band sources. Quartz optics.
This unit includes a beam-splitter quartz plate to send signals to a reference normalization photodiode. It also includes a port accessible through a flipping mirror for laser excitation. All quartz optics.
