Hitachi' s Superior Fluorescence Technology has
created a new generation of fluorescence spectrometers.
F-7100 is the evolution of the robust and reliable F-7000 with the latest
optical technology and improved analytical performance.
With the highest level for 3D fluorescence spectra,
F-7100 can be used in a wide range of applications from the cutting edge
research to quality control: Applications.
21 CFR Part 11 Compliant software available.
Best-in-Class" Analytical Signal-to-Noise. 360 of
S/N (P-P) and > 1,200 of S/N (RMS)
Increased sensitivity 1.5x compared to conventional
instruments
Due to its enhanced sensitivity (1.5x higher), weak
signals can be detected with very low noise levels.
An example of the high sensitivity analysis for
fluorescein is shown. The F-7100 detected fluorescence in the order of 1x10-13 mol/L
(sub-picomol) compared with a blank sample (purified water); a useful
calibration was obtained in the ultra-trace range.
Industry leading lamp lifetime
Light source with 5x*¹ longer lifetime compared to
conventional instruments – lifetime of 2,500 hours*² –
The fast-speed scanning enables users to carry out
measurements that have been difficult with conventional instruments. In this
example, an isomerization process of coumarin in kerosene was traced by
spectrum measurement at 2-second intervals and displayed as a 3-D time-scan
spectrum. This is a new function in the F-7000.
Previously, a quick reaction which occurs within 1 minute could be measured
only by using the fixed wavelength method. The F-7000 is capable of following
such a quick reaction because of its fast scanning, measuring the entire
wavelength range within 1 second.
FL intensity standardization to correct for
fluorecence intensity variation over time and between instruments
The variations in the fluorescence intensity over time
and between instruments can be corrected. Fluorescence intensity is affected by
changes in lamp brightness, room temperature, optical system, etc. The
fluorescence intensity of the standard sample is measured, and the sample
fluorescence intensity is converted to the fluorescence intensity relative to
the standard sample. This standardization is also used for the intensity
comparison between different instruments, including the analysis of humic substances
in environmental water (conversion to quinine sulfate), the analysis of
chlorophyll in water (conversion to fluorescein), and the specified value for
reagent purity (conversion to quinine sulfate).
