In 1967, JASCO launched the FP-1, which was the first in a long line of spectrofluorometers.

The FP-8050 Series is the latest range of instruments developed to provide accurate measurements for bio- and material sciences, from a simple entry level model for fluorescence spectral measurements and sensitive quantitation to the advanced models developed for demanding research applications including spectral correction and quantum yields.

System Features

The FP-8050 Series

The FP-8050 Series of spectrofluorometers includes four different instruments that provide solutions for the broadest range of applications including QC, biomolecular structural studies, environmental monitoring and advanced materials science. The FP-8050 Series has many flexible options for academic or industrial research, teaching, or use in quality control labs. Users can have the greatest confidence in their measurements, with an optical bench specifically designed for the highest sensitivity, widest dynamic range, and exceptional spectral purity with automatic cut-off filters to exclude higher order diffraction.

The FP-8050 Series combines a compact design with the largest range of accessories together with Spectra Manager™ Suite, a comprehensive data platform that gives you complete control over measurement, analysis and data archiving. In addition to the standard analysis programs, JASCO has developed many different applications software for dedicated sample measurement.

Outstanding sensitivity and linear dynamic range

The high-throughput optical system and low noise signal processing of the FP-8050 Series results in a high signal-to-noise (S/N) performance up to 8,500:1 (RMS). In addition, the dynamic range of FP-8050 Series has been developed to provide up to 7 orders of magnitude.

Higher-order light cut-off filters

In order to remove peaks originating from higher order diffracted light, cut-off filters appropriate to the measurement wavelength should be used. The models FP-8350, FP-8550, and FP-8650 include cut-off filters that are switched automatically as the wavelength range is set by the user.

Accurate spectral correction

Spectral correction should be made to any fluorometer for the measurement of accurate and reliable spectral data. All models in the FP-8050 Series can be spectrally corrected using a simplified procedure. JASCO has a range of calibration standards for spectral correction, including standard light sources and Rhodamine B.

Auto-adjustment of detector gain and sensitivity

The FP-8050 Series includes both Auto-Gain and Auto Sensitivity Control System (SCS), which automatically
adjust the detector gain and sensitivity for optimum measurement. Auto-Gain automatically adjusts the gain of the signal from the detector so that the S/N is optimized throughout the entire scan range for spectral measurement, and weak fluorescence peak shapes can be observed against scattered light with a high S/N. The Auto-SCS allows the user to create calibration curves for a wide concentration range without having to manually change the instrument sensitivity settings.

Automatic Accessory Recognition

Accessories are automatically recognized when installed in the instrument. Spectra Manager™ logs the accessory name and serial number; this information is saved in the data fi le for a complete record of the measurement.

Validation program

The Validation program includes a full suite of tests to validate instrument performance. When executed, simple prompts guide the user on how to perform the tests. All instruments in the FP-8050 Series include a
mercury lamp as standard for wavelength calibration.

Daily Check program

The Daily Check is a simple alternative to the Validation program; a less comprehensive performance check
can be made at any time for continuous performance monitoring. After starting the Daily Check program, a timer is activated, and sample measurement is executed automatically after a predetermined stabilization time. The batch display lets the user check the cumulative data over a period of time.

Long-life light source

Continuous output Xenon arc lamps off er the greatest sensitivity. For the longest and highest performance, the FP-8050 Series now includes a newly designed Xenon arc lamp with prolonged lifetime, with long-term stable measurements, reduced maintenance and lower running costs.
