Thermo scientific hollow cathode lamp full#

We offer a full line of single and multi-element lamps available with or without data coding for direct compatibility with your Thermo Fisher AA. For maximum flexibility from your Thermo Scientific iCE 3000 Series Atomic Absorption spectrometer, a huge range of pre-coded and un-coded Thermo Scientific Hollow Cathode Lamps are available, to handle your chosen elements for analysis. Also, by establishing a reference system from standards of known concentration, unknown samples can be analyzed quantitatively. Analytical West offers high-quality 1.5-inch hollow cathode lamps for direct use in Atomic Absorption instruments manufactured by Thermo Unicam. Because element concentration is a function of its wavelength intensity, the concentration of the target element can be determined. Following dispersion of these wavelengths (including the characteristic wavelength of the analyte), the AAS instrument detector measures wavelength intensity. Atomizer and monochromator instruments are key to making the AAS device work.Īfterwards, the analyte is excited by different light sources and emits a mixture of wavelengths. This reduced intensity is characteristic of a given element and helps to identify it, as well as to determine its concentration.ĪAS takes advantage of different radiation wavelengths that are absorbed by different atoms. Fisher Scientific Adam Equipment National Scientific Sigma Aldrich EP. When absorption occurs, the result is a light spectrum that has reduced light intensity in one or more of its areas. Unicam / Thermo coded 37mm hollow cathode lamp for Lanthanum analysis. This light source has been set to defined wavelengths, and the metal atoms in the sample absorb these wavelengths (or not). The sample is then exposed to a source of radiation, which typically originates from a light source. In graphite furnace AAS, the liquid sample is introduced into the cuvette directly, where it is transformed into a fine mist. Afterwards, this mist is fed into a flame to break up any remaining molecular bonds.

In the case of flame AAS, this involves atomizing the sample, which involves the creation of a fine mist dispersion. Whether you require a single dedicated element or a multi-element. Sample preparation and introduction involve rendering a liquid or solid sample into a state that the instrument can process for elemental analysis.
