Atomic Absorption Spectrometer Fiber SMA-DUVYZ-02
Atomic absorption spectrometers (AAS) measure elemental concentrations, particularly trace/ultratrace metals. Flames or graphite furnaces heat sample molecules to atomic form. Characteristic source lines are absorbed by corresponding atoms while passing through the flame/furnace. Absorbance is proportional to atomic concentration, enabling elemental determination. Fibers transmit optical signals through AAS paths. The source lists hollow-cathode lamps and electron multipliers as common sources emitting elemental resonance lines. Fibers carry selected wavelengths to samples and then transmit remaining, partially absorbed light to detectors. 1. Material: stability at high analytical temperatures and high transmission in the measured band. 2. Diameter/count: determine transmitted light quantity/quality, sensitivity, and stability. 3. Arrangement/layout: efficient source-to-sample-to-detector transmission with minimal loss. 4. Chemical resistance: corrosion resistance for generally liquid samples and long use. 5. Thermal resistance: continuous operation near hot flames/furnaces without degradation. Fibers improve flexibility and convenience for complex or remote paths, while quality/performance must meet analytical needs. Advances broaden AAS applications. AAS quantitatively measures atomic composition and elemental concentration. Fibers carry source-to-sample and sample-to-detector signals, improving efficiency and detection. Appropriate fiber types/designs benefit source guidance, absorbed-light collection, remote/multichannel detection, and signal-to-noise ratio, expanding performance and practical applications.
