Core Product Features

1. Integration of Multiple Spectroscopic Technologies

Blazed Holographic Concave Grating Optical System: Co-developed with internationally renowned enterprises, adopting original imported optical components, featuring low stray light, high resolution, and excellent test accuracy.

High-Precision Chopper System: Adopts a multi-CPU collaborative control architecture to achieve precise regulation of the chopper system. Leveraging the long-life characteristic of phosphorescence, it effectively avoids interference from Rayleigh scattering, Raman scattering, and stray light, providing reliable guarantee for trace analysis.

Phosphorescence Measurement Function: Can accurately measure phosphorescence lifetimes as short as 1ms, adapting to the testing needs of various types of samples.

High-Speed 3D Scanning: Equipped with fluorescence 3D scanning function, it can quickly locate the fluorescence information of unknown samples, greatly shortening the analysis time and improving work efficiency. The generated color 3D spectrogram presents a more intuitive visual effect for academic research.

Synchronous Fluorescence Method: Supports constant-wavelength synchronous fluorescence spectrum scanning, which can reduce the overlap of fluorescence peaks in the measurement of multi-component samples, narrow the spectrum, and reduce the impact of scattered light.

2. High Sensitivity, High Speed, and High Reliability

Ultra-High Sensitivity: Unique optical system design combined with advanced digital signal processing technology, delivering excellent signal-to-noise ratio, easily meeting the testing requirements of high-resolution and ultra-trace samples.

Low Sample Consumption: Both excitation and emission beams adopt a unique horizontal slit design, which improves detection sensitivity while significantly reducing sample extraction volume.

High-Speed Scanning Performance: With industry-leading scanning speed, combined with an advanced data acquisition system, it can obtain abundant data points during high-speed scanning, ensuring the authenticity and accuracy of test spectra.

Light Shielding Protection System: The excitation side is equipped with a light-shielding shutter to effectively reduce sample exposure time and protect photosensitive samples; the emission side is equipped with a gated light shutter to prevent the receiver from direct exposure to strong light, extending the service life of the receiver.

3. User-Friendly Design

Dual Background Subtraction Function: The supporting software workstation supports dual background subtraction operation. Users can flexibly select corresponding function keys according to different test backgrounds to automatically subtract the sample’s own background and directly calculate the fluorescence intensity and concentration of the test solution.

Rich Accessory Configuration: Provides a variety of practical accessories, including solid sample holders, automatic 8-channel sample cell holders, water bath constant temperature magnetic stirring sample cell holders, polarization accessories, and fluorescence water bath constant temperature systems, helping to solve various complex application analysis problems.

Audit Trail Function: The instrument’s supporting software has a “three-level management authority” function, complying with the requirements of relevant international testing standards.

Professional Certification Service: Offers 3Q certification and installation services to ensure the standardization of instrument installation and use.
