Core Features
1. Integration of Multiple Spectroscopic Technologies
High-Precision Scanning Mechanism: The monochromator is equipped with an imported high-density lead screw scanning mechanism, combined with a multi-CPU collaborative motor control system. This enables high-precision and high-repeatability spectral scanning, ensuring the accuracy of detection data.
High-Speed 3D Scanning Function: It can quickly locate the fluorescence information of unknown samples, significantly shortening the analysis cycle of unknown samples and improving work efficiency. The generated color 3D spectra have both professional and visual presentation effects, making them suitable for academic research demonstrations.
Photolabile Sample Protection Design: The built-in light chopper function can effectively shorten the exposure time of samples under the excitation beam, avoiding changes in the properties of samples prone to photochemical reactions and ensuring the analysis precision of continuous experiments.
2. High Sensitivity, High Speed, and High Reliability
Optimized Sample Usage: Both the excitation and emission beams adopt a horizontal slit design. While improving detection sensitivity, it reduces the sample extraction volume, lowering experimental costs and sample loss.
Light Shielding Protection System: The emission side is equipped with a gated light shutter, which can prevent the detector from being directly exposed to strong light, extend the service life of core components, and ensure the long-term stable operation of the instrument.
3. User-Friendly Characteristics
Dual Background Subtraction Function: The supporting software workstation supports dual background subtraction. Users can flexibly select corresponding operations according to different test backgrounds, and the software can directly calculate the fluorescence intensity and concentration of the sample solution to be tested, simplifying the data processing process.
Rich and Practical Accessories: It can be matched with a variety of accessories, including solid sample holders, automatic 8-channel sample cell holders, water bath thermostatic magnetic stirring sample cell holders, polarization accessories, and fluorescence water bath thermostatic systems. These accessories meet the application and analysis needs in different scenarios.
Audit Trail Function: The instrument’s supporting software has a “three-level management authority” function, which complies with the requirements of relevant industry testing standards and ensures the traceability and compliance of the experimental process.
Professional Certification Service: 3Q certification installation service is provided to ensure that the instrument installation and use meet international general standards.

How does the spectral bandwidth setting on the Atomfair FS-516 affect its signal-to-noise ratio and detection sensitivity for trace analysis?
The FS-516 achieves a sensitivity of >150:1 (Water Raman Peak) and offers selectable spectral bandwidths of 1.0 nm, 2.5 nm, 5.0 nm, 10.0 nm, and 20.0 nm for both excitation and emission monochromators. Narrower bandwidths improve wavelength resolution but reduce photon flux, lowering signal intensity; wider bandwidths increase signal strength but may compromise resolution. The instrument's high-precision scanning mechanism and built-in light chopper maintain high repeatability and minimize photobleaching, enabling reliable trace analysis across bandwidth settings.
What sample volume and cuvette types are compatible with the Atomfair FS-516, and can it analyze solid samples?
The FS-516 requires a minimum sample volume of 0.5 mL when using a 10 mm standard cuvette. For solid samples, an optional solid sample holder accessory is available. The excitation and emission beams use a horizontal slit design that reduces sample extraction volume while maintaining high sensitivity, and the instrument supports additional accessories such as an 8-channel automatic sample cell holder, water bath thermostatic magnetic stirring holder, and polarization accessories for varied application needs.
What safety and handling features protect photolabile samples and the detector in the Atomfair FS-516, and does it require special ventilation?
The FS-516 incorporates a built-in light chopper that limits sample exposure to the excitation beam, preventing photochemical degradation of labile compounds. A gated light shutter on the emission side shields the detector from intense stray light, prolonging component life. The 150 W high-pressure lamp features automatic ozone removal, reducing the need for external ventilation. The instrument also includes a light-blocking shutter and comes with 3Q certification installation to ensure safe, compliant operation.
The Atomfair-FS-516 Molecular Fluorescence Spectrophotometer delivers high-sensitivity detection (P-P >150:1 water Raman peak) with a 150W high-pressure lamp and concave holographic gratings, supporting wavelength, time, photometric, and 3D scanning across 200–760nm (extendable to 900nm with a special PMT). Its dual background subtraction, light chopper for photolabile samples, and gated emission shutter provide robust analytical precision and detector protection, though the 45kg weight and Windows-only software require dedicated lab infrastructure.
Positive
- High sensitivity and repeatability: With a P-P sensitivity >150:1 (water Raman peak) and a high-density lead screw scanning mechanism, the instrument ensures precise, repeatable spectral measurements critical for trace-level fluorescence analysis in food safety and environmental testing.
- Photolabile sample protection: The built-in light chopper reduces sample exposure to the excitation beam, preventing photochemical degradation during continuous experiments, which is essential for analyzing light-sensitive compounds like aflatoxins or upconversion materials.
Trade-offs
- Heavy and bulky footprint: At approximately 45kg and 670mm×540mm×310mm, the instrument requires a dedicated, stable lab bench and may be challenging to relocate or install in space-constrained facilities.
- Software and OS limitations: The supporting software only runs on Windows 7 and Windows 10, which may pose compatibility issues with newer operating systems or lab IT environments, and the USB2.0 interface limits data transfer speeds for large 3D spectral datasets.
