Hitachi Fluorescence Spectrophotometer F-4700 It's in the previous generation model F-4600 On the basis of the update and upgrade, the overall performance has been further improved. Sensitivity and wavelength scanning speed are two important factors in choosing a fluorescence spectrophotometer. F-4700 With previous generation models^*Compared with this, the sensitivity and scanning speed are increased by 1 times respectively. at the same time, F-4700 The new long-life xenon lamp is used, and the service life is extended to 1,000 hours compared with the consumable xenon lamps used in the previous generation models. also, F-4700 It is also equipped with fluorescent fingerprint measurement function and daily difference change correction function to make operation easier.

Features

Higher sensitivity detection system

F-4700 Continue to use the advanced technology of Hitachi etching gratings and inherit F-4600 The stable and reliable optical system is achieved by improving the excitation side light energy, improving the performance of the emission side detector, and optimizing the signal processing method, so as to achieve higher sensitivity performance.

Water Raman scattered S/N contrast

By water Raman scattering with previous generation models S/N Comparison of test results, F-4700 The sensitivity is 1.5 times that of previous models, and even weak signals can achieve low noise detection.

Example of determination of trace fluorescein regions

Ultra-high sensitivity is more obvious in actual analysis cases, Blank（ Pure water) for reference, use F-4700 Detectable as low as 1 ×10^-12mol/L（picomol） fluorescein of order of magnitude. From the linear curve diagram, we can see that even in the trace area, a good linear relationship can be obtained.

Long-life light source

F-4700 The new xenon lamp is adopted and the improved lamp power supply increases the brightness of the light source and effectively extends the service life of the xenon lamp to 1,000 hours. Extending the light bulb replacement cycle can reduce the cost of consumables and reduce the operating burden of light bulb replacement.

①Three-dimensional spectral detection

Three-dimensional fluorescence spectroscopy can directly characterize the relationship between the excitation wavelength and the emission wavelength of the sample, and obtain a large amount of data at one time in a short time to quickly obtain better excitation and emission wavelengths. F-4700 Have 60,000 nm/min The ultra-high-speed scanning speed greatly shortens the measurement time. After obtaining the three-dimensional spectrum, the excitation emission spectrum can be selected at will and viewed and saved in the form of a two-dimensional spectrum.

②Fluorescence intensity standardization function

The fluorescence intensity will be affected by factors such as light source brightness, room temperature changes, and changes in optical system state. The fluorescence intensity standardization function can correct the echotime and day-daily variation of fluorescence intensity.
