Atomic Fluorescence Spectroscopy explained this technique does not have interferences, such as hydrocarbons, hydrogen sulfide, and ammonia, which are often problematic for traditional detection methods. Atomic Fluorescence Spectroscopy should not be confused with Atomic Absorption Spectroscopy (AAS). In AAS, a light source of known wavelength and intensity is passed through a sample of interest. Some of the energy of the source light is absorbed by the sample as it energizes electrons in the material from the ground state to an excited state...

Heraeus Noblelight LLC – Optics + Analytics
Atomic Absorption Spectroscopy (AAS) Heraeus Hollow Cathode Lamps are mainly used in Atomic Absorption Spectrometry (AAS). AAS uses the absorption of light to measure the concentration of gas-phase atoms. Since samples are usually liquids or solids, the analyte atoms must be vaporized in a flame or graphite furnace. The atoms absorb ultraviolet or visible light and make transition to higher electronic energy levels. The analyte concentration is determined from the amount of absorption. AAS is a quantitative method that can... (read more)Browse Lamps Datasheets for Heraeus Noblelight LLC – Optics + Analytics

NEW! Jerome® J505 Mercury Vapor Analyzer is designed and calibrated to elemental mercury vapor only. This technology lends itself to fewer interferences than competing Atomic Absorption Spectroscopy. How does this compare with Atomic Absorption Spectroscopy?. Atomic Absorption Spectroscopy does have interferences with hydrocarbons. Interferences include high readings, degradation of reflective surfaces-corrosion, and condensed water vapor on mirrors. Introduction. Whether it is fluorescent lighting, dental fillings, antique switches, gold... (read more)
Laser Induced Breakdown Spectroscopy . Laser Induced Breakdown Spectroscopy or LIBS has become the common acronym for element detection via laser induced plasma. This permits real-time qualitative identification of trace elements in solids, gases, and liquids via optical detection of elemental emission spectra. Using this technique, little or no sample preparation is required and calibration-free quantitative analysis has been reported without matrix effects.
