Compact LED Spectrophotometer 200~900nm 220v

The Hamamatsu 150W Xenon lamp serves as the light source, providing the excitation for the system. The standard set of the instrument is equipped with an interference optical filter, which has a central wavelength of 365nm and a bandwidth of 10nm. Additionally, an optional interference optical filter with a wavelength range of 200-850nm and a diameter of 25mm can be provided upon user request.

The emission monochromator utilizes a C-T diffraction grating, enabling a detection wavelength range of 200~900nm with a bandwidth of 10nm. The wavelength accuracy is ±1nm, and the wavelength repeatability is ≤0.5nm.

The instrument's sensitivity is demonstrated by the Raman peak of water in a 1 cm quartz fluorescence cuvette, which achieves a signal-to-noise ratio (S/N) of ≥150. The linear measurement (r) is ≥0.995, ensuring reliable and accurate results.

The instrument's stability is better than 1.5%/10min, providing consistent performance over time. The power source requirements are 220V±22V, 50Hz±1Hz, ensuring compatibility with a wide range of electrical systems.

The response time of the instrument can be adjusted in 6 stages, ranging from 0.1s to 4s, allowing users to optimize the measurement speed based on their specific needs. The fluorescence display value can be shown in the range of 0.00-600.00.

Data transmission is supported via the USB2.0 interface, enabling seamless integration with computer systems. Two modes are available: fluorescence intensity and luminous intensity. Under the fluorescence intensity mode, users can perform fluorescence scanning, kinetic determination, and quantity analysis.

The high-performance sensitivity of the instrument, demonstrated by the Raman peak of water with an S/N of ≥150, simplifies the measurement of low-detection samples. The 10-stage gain adjustment for emission spectrum scanning allows for both high-speed, low-S/N scanning and precise scanning, with the ability to complete a full spectrum scan in as little as 1 second.

The instrument supports both off-line and on-line modes. In the off-line mode, the built-in computer system provides features such as fluorescence intensity measurement, concentration direct reading, auto 0 adjustment, and auto background subtraction. In the on-line mode, users can utilize quality and quantity software to control data acquisition and analysis through the USB2.0 interface.
