Hitachi's unique concave diffraction gratings combined with a low noise detection system result in an excellent signal-to-noise ratio (S/N ≥ 800 RMS, Raman band of water using 5nm slits), allowing measurement of fluorescein with sensitivity in the order of 1 x 10-12 mol/l.

Hitachi fluorescence spectrophotometers offer a wide dynamic range of 6 or more orders of magnitude. This is the result from our unique circuit-processing technology where our fluorescence spectrophotometers switch gain automatically and allow measuring samples with low and high fluorescence intensity under the same conditions. This eliminates the need to prepare multiple calibration curves for a range of concentrations.

The Hitachi F-2700/F-2710 fluorescence spectrophotometers's variable slit width works well for samples displaying sharp peaks or for samples with broad band peaks.

The F-2700/F-2710 Fluorescence Spectrophotometers offer optional accessories for performing full range spectral correction for both the Excitation and Emission monochromators. This allows eliminating spectral distortions in your data resulting from the variation in power distribution from lamp to lamp, efficiency curves of the diffraction gratings and sensitivity of the detector. This is a desirable feature when publishing data or when comparing data from instrument to instrument. The picture below shows a measurement for NIST SRM 936.

Neutral density screens reduce the excitation light when narrow slits are not available. In a variable band pass instrument, screens are useful for adjusting the relative intensity to a desirable Y-scale position for a set of samples. Decreasing the slit width however results in a higher reduction in intensity than the addition of a screen.
