    What is Atomic Fluorescence Spectroscopy?

    In atomic fluorescence spectroscopy, similar to the related technique of atomic absorption spectroscopy, a sample absorbs light at a particular wavelength to promote its electrons from its ground electronic state into an excited state. From this excited electronic state, the electron drops down to a lower electronic state, emitting a photon with a specific wavelength in the process. By measuring the intensity of the emitted light at particular frequencies, it is possible to determine the concentration of the element in question via atomic fluorescence spectrometry.

    What type of elements can be detected by the LUMINA AFS?

    The LUMINA series of Atomic Fluorescence Spectrometers provide sub-trace detection and elemental analysis of hydride-forming elements. The unique vapor/hydride generator provides enhanced sensitivities and reduced interferences for detection of Mercury (Hg), Arsenic (As), Cadmium (Cd), Zinc (Zn), Bismuth (Bi), Selenium (Se), Tellurium (Te), Antimony (Sb), Tin (Sn), Germanium (Ge), and Lead (Pb).

    What is the detection limit of the LUMINA AFS systems?

    Detection limit for the following elements is specified in table in below:

    ElementDetection Limit (μg/L)RSD (%)
    As, Se, Pb, Bi, Sb, Te, Sn0.01<1.0
    Hg, Cd0.001<1.0

    What type of atomizer and gas/liquid separator technology is used in the LUMINA Atomic Fluorescence Spectrometer?

    The LUMINA AFS system uses a quartz tube furnace with an interference-reducing Ar-H2 diffusion flame. This flame is ignited automatically within the instrument. The LUMINA AFS system is also equipped with a two-stage gas/liquid separator and a filtered, integrated exhaust system that can efficiently decontaminate pollutants during sample preparation and delivery steps.

    Can Atomic Fluorescence Spectroscopy be used for Mercury (Hg) detection?

    Yes, the LUMINA AFS system utilizes the Cold Vapor method for mercury detection. Mercury analysis is a critical component of food and water safety, agriculture, and environmental monitoring. Samples must be digested prior to analysis to ensure accurate analyte measurements.

    Is Atomic Fluorescence Spectroscopy a recommended method for Mercury (Hg) detection in environmental samples?

    Yes, the Cold Vapor method used by the LUMINA Atomic Fluorescence Spectrometer is recommended by the USFDA for detection of Mercury at ppb or sub-ppb levels.

    Is LUMINA AFS competitive against ICP method for Mercury (Hg) detection?

    Yes; for example, the LUMINA AFS system has a detection limit for mercury for 1ppt, which is comparable to literature reported detection limits for mercury with ICP-MS. Additionally, the plasma temperatures utilized in ICP-MS may be too hot for accurate mercury analysis, leading to premature mercury decomposition and thus unreliable results.

    Can the LUMINA AFS instrument be integrated with an autosampler?

    Yes, the LUMINA includes an optional XYZ autosampler for sample introduction that hosts a maximum of 192 standard cup/test tube sample racks. It is compatible with standard solvent extraction test tubes, ICP test tubes, and custom-made trays.

    What type of light sources do the LUMINA AFS systems use for elemental detection?

    The LUMINA Atomic Fluorescence Spectrometers are equipped with specially-designed high intensity Hollow Cathode Lamps (HCL) with 2-channel independent power supplies, providing improved sensitivities and lower detection limits. It also features dual channel, simultaneous two-element analysis, using a computer controlled pulsed light sources.
