FLUORAT®-02-PANORAMA Spectrofluorometer
|
|
FLUORAT®-02-PANORAMA spectrofluorometer is the most sophisticated instrument among the FLUORAT®-02 family. It is intended for scientific research, chromatographic analysis, and for operation as part of multimodule automatic measuring facilities. The spectral regions in the excitation and detection paths are set by built-in fast monochromators. The monochromators are controlled independently, so that the analyst can program any of their operation functions in the process of measuring, in particular, the spectra can be synchronously scanned.
A proprietary optical scheme provides the high sensitivity of the
instrument, especially in the UV spectral range, where the isolation
of a spectral interval using a light filter is difficult. The instrument
is controlled either from a built-in keypad or from an external computer.
The program-controlled computer interface implements the «virtual
device» operating mode. In this mode, the current status of all the
units and processes occurring in the instrument are displayed on the
screen..

Extended capabilities:
- Analysis of liquid and solid samples by the luminescence spectra
- Chromatographic analysis of several components during single eluation
- Synchronous and two-dimensional scanning of the spectra
in both excitation and luminescence detection paths
- Precise measurements of luminescent kinetic processes.
- Detecting and recording of luminescence and luminescence
excitation spectra, or synchronous luminescence scanning
spectra.

FLUORAT®-02 PANORAMA incorporates two monochromators in the luminescence
excitation and detection paths, which are arranged in a compact
two-level configuration, a Xenon flashlamp as a light source, and
a PMT as a detector of luminescence signals. To enhance the measurement
accuracy, a correction with respect to the reference and transmission
paths is used. The monochromators employ 900 - l/mm concave diffraction
gratings with 100-mm radius of curvature. The wavelength is set
either from a keyboard or using a computer control program.
