Double Beam Scanning Spectrophotometer Uv Fluorescence Spectrometer Instrument

High-speed Fluorescence spectrophotometer

This model high-speed fluorescence spectrophotometer is suitable for measurement from ultraviolet region to visible light region. It supports stand-alone and online modes. In stand-alone state, the built-in microcomputer system is used to provide fluorescence intensity measurement, direct reading of concentration, automatic zero adjustment, and automatic background subtraction. and other functions, the online state can use the upper-level software to control the instrument and data acquisition and analysis through the USB2.0 interface.

Features

1. Two operating modes, fluorescence intensity and luminescence intensity, can be selected. In the fluorescence intensity mode, fluorescence spectrum scanning, fluorescence kinetics measurement and quantitative analysis can be performed.

2. The signal-to-noise ratio of the Raman peak at the excitation wavelength of 365nm is >150 (p-p), and the excellent high detection sensitivity can make the determination of samples with low detection limit very accurate and simple.

3. Provide 10 emission spectrum scanning speed options, including high-speed low-noise scanning and fine scanning. Among them, the ultra-fast scan is 30000nm/min, which can complete the full spectrum scan in 1 second, and has the intelligent pre-scan function, which can quickly display the spectral information of the unknown sample, automatically exclude the influence of other scattering peaks and frequency doubling peaks, and determine the measurement parameters. Locate fluorescence emission peaks.

4. Support stand-alone and online modes. In stand-alone state, the in-machine microcomputer system provides functions such as fluorescence intensity measurement, concentration direct reading, automatic zero adjustment, and automatic background subtraction. In online state, qualitative/quantitative software can be used through the USB2.0 interface. Instrument control and data acquisition and analysis.

5. The high-intensity 150W xenon lamp is continuous spectrum, which can provide excellent test stability in the wavelength range of 200nm to 900nm.

6. It has the function of normalizing the fluorescence value, which can eliminate the problem of incomparability of the fluorescence values ​​between different fluorescence photometers, and facilitate the unified evaluation of the experimental reports of students in college teaching.

7. The qualitative/quantitative software is rich in functions. The emission spectrum wavelength scanning menu can provide spectrum scaling, multi-spectrum comparison, spectrum operation, peak-valley detection, peak area calculation and 1-4 order derivative spectrum functions; the quantitative test menu can use the standard curve method Detect sample concentration with undetermined coefficient method, provide first-order linear regression, second-order or third-order linear fitting, and can customize the concentration unit.

8. A variety of measurement accessories, including single-hole cuvette holder, multi-purpose fluorescence sample holder, 200μl microcentrifuge tube fluorescence measurement, capillary micro-sample holder, semi-automatic fluorescence sample injection, single-hole cuvette adapter, membrane sample holder , powder sample holder and sheathed cuvette holder, etc., trace samples as low as 5μl can be easily measured, and it is also suitable for high-concentration fluorescence detection and solid-state fluorescence detection, which can meet various application requirements.

9. The compact model can save a lot of desktop space
