Hitachi Fluorescence Spectrophotometer F-7100 It's in the previous generation model F-7000 The basic performance has been further improved. Sensitivity is one of the important factors in choosing a fluorescence spectrophotometer. F-7100 Compared with previous generation models, the sensitivity is 1.5 times higher, and the Raman signal-to-noise ratio of water is as high as above 20,000. at the same time, F-7100 It uses long-life xenon lamps, which can last up to 5 times longer than the consumable xenon lamps used in previous generation models. F-7100 Configure the fluorescent fingerprint measurement function and the daily difference change correction function to make the operation easier.

Features

The highest sensitivity detection system

Example of determination of trace fluorescein regions

The left image indicates Blank（ Pure water) is a reference, ultra-high sensitivity detection example. use F-7100 Detectable as low as 1 ×10^-13mol/L（ subpimole) fluorescein of the order of magnitude. From the linear curve diagram, we can see that even in the ultra-triple area, good linear relationships can be obtained.

Long-life light source

Comparison of lamp service life

F-7100 The new xenon lamp is adopted and the lamp power is improved, which improves the brightness of the light source and effectively extends the service life of the xenon lamp. Extending the light bulb replacement cycle can reduce the cost of consumables and reduce the operating burden of light bulb replacement (as shown in the picture on the left above). As can be seen from the picture above, F-7100 Excellent performance, even if xenon lamp is used close to 2500 h， It can also maintain high sensitivity.

High-speed scanning, speed up 60,000 nm/min ‐Three-dimensional time-scanning fluorescence spectroscopy tracking and monitoring chemical reaction process

Three-dimensional time-scanned fluorescence spectrogram of coumarin in environmental applications

Traditional fluorescence spectrometers are difficult to achieve chemical reaction monitoring, but F-7100 Ultra-high speed scanning speeds make this measurement easy. In this example, the fluorescence spectroscopy measurement tracks the isomerization process of coumarin in kerosene over a 2-second interval and is displayed in a three-dimensional time scan spectrum.
Previously, rapid chemical reactions that occurred within 1 minute could only be monitored by a fixed wavelength method. because F-7100 The fast scanning capability can complete measurements of the entire wavelength range within 1 second, so it can track such a fast reaction process.

Fluorescence intensity standardization function —Correcting changes in fluorescence intensity and instrument categories—

Fluorescence intensity standardized screen

The slight difference in intensity caused by fluorescence due to different test dates can be corrected.
The fluorescence intensity will be affected by changes in the brightness of xenon lamps, room temperature changes, optical systems, etc. Use the fluorescence standardization function to convert the fluorescence intensity of the sample with the fluorescence intensity of the standard sample. This function makes the fluorescence peak intensity values tested by different instruments at different times comparable.
