How do the selectable spectral bandwidth gears affect fluorescence measurement resolution and sensitivity on the Atomfair-FS-647?
The Atomfair-FS-647 offers five selectable spectral bandwidth gears (1, 2.5, 5, 10, 20 nm) for both excitation and emission. Narrower bandwidths (e.g., 1 nm) provide higher spectral resolution for resolving fine spectral features, but reduce signal intensity, while wider bandwidths increase sensitivity at the expense of resolution. The instrument also achieves a step resolution of 0.2 nm, allowing fine wavelength control independent of the bandwidth setting.
What sample forms are compatible with the Atomfair-FS-647, and what accessories are required for solid sample analysis?
The Atomfair-FS-647 is compatible with liquid, powder, thin film, and other sample forms. For solid sample analysis, the instrument includes dedicated solid sample test accessories and fluorescence cuvettes, enabling direct measurement of powders and thin films without complex preparation.
What is the minimum sample volume for standard cuvette measurements on the Atomfair-FS-647, and how does the light-shielding protection system benefit photosensitive samples?
The Atomfair-FS-647 requires only 0.5 mL of sample for a 10 mm standard cuvette, minimizing sample consumption. Its built-in light-shielding protection system reduces sample exposure time to the excitation beam, protecting photosensitive compounds from photodegradation and prolonging detector life.
The Atomfair-FS-647 Fluorescence Spectrophotometer is a steady-state fluorescence system with a 200-900nm spectral range, 150W xenon lamp, and Hamamatsu PMT, delivering a signal-to-noise ratio above 300:1 (P-P) and a minimum spectral bandwidth of 1nm. Its low sample volume requirement (0.5mL in a 10mm cuvette) and support for multiple sample forms (liquid, powder, thin film) make it suitable for materials, pharmaceutical, and environmental analysis, though its steady-state design limits time-resolved measurements without additional accessories.
Positive
- High sensitivity and wide spectral range: With a signal-to-noise ratio above 300:1 (P-P) and a 200-900nm spectral range, the instrument supports ultra-trace detection and covers UV-visible to near-infrared fluorescence, chemiluminescence, and bioluminescence measurements.
- Low sample volume and versatile sample compatibility: Requiring only 0.5mL for a 10mm cuvette and supporting liquid, powder, and thin film samples, the system minimizes sample consumption and adapts to diverse application needs in materials, pharmaceutical, and environmental testing.
Trade-offs
- Steady-state measurement limitation: As a steady-state fluorescence spectrometer, the instrument is not designed for time-resolved fluorescence lifetime measurements without additional accessories, which may limit certain kinetic or dynamic quenching studies.
- Xenon lamp operational requirements: The 150W high-pressure xenon lamp requires proper handling and periodic replacement, and the light-shielding protection system, while protective, may reduce throughput for photosensitive samples if exposure time is not optimized.
