Compact LED Spectrophotometer 250~600nm (220V/50Hz)

Specifications:

In the single machine state, the internal computer system provides functions such as fluorescence intensity measurement, concentration direct reading, automatic zero adjustment, and automatic background deduction. The on-line state can be controlled by qualitative/quantitative software, and data acquisition and analysis can be performed using a USB2.0 interface. The normalization function of fluorescence value in quantitative analysis can eliminate the problem of unequal fluorescence value among different fluorescence photometers. The emission spectrum wavelength scanning menu provides functions like map scaling, multi-map comparison, Atlas operation, peak valley detection, peak area calculation, and 1-4 order derivative spectral functions. The quantitative test menu can use the standard curve method and undetermined coefficient method to detect sample concentration.

The high reliability cold light source has the advantages of low background, low power consumption, low temperature, long life, high strength, and more energy-saving and environmental protection.

At the 365nm excitation wavelength, the water Raman peak signal-to-noise ratio is greater than 90 (P-P), and the high detection sensitivity is suitable for ultra-low concentration sample measurement.

The instrument provides 10 transmission spectrum scanning speed selections, including high-speed low-noise scanning and fine scanning. The ultrafast scan is 30000nm/min, which can complete a full scan in one second.

It has the function of intelligent pre-scanning, which can quickly display the spectral information of unknown samples, automatically exclude the influence of other scattering peaks and frequency doubling peaks, and determine the best measurement parameters and locate the fluorescence emission peak.
