WebThe PinAAcle 900H AA spectrometer, fitted with an HGA graphite furnace and deuterium background correction, has proved its ability to successfully control digested rice sample matrix – the system offers first … WebThe Deuterium lamp emits UV radiation continuously. This is parallel to the hollow cathode lamp. A spinning chopper is present to alternately pass radiation from the cathode lamp and the Deuterium lamp into the atomizer. Background correction is accomplished by modifying the monochromator slit, which subtracts deuterium radiation.
WebSep 15, 2006 · To receive accurate analytical results, an efficient background correction is necessary applying deuterium lamp, Zeeman or Smith-Hieftje background correction techniques [9]. ... WebMar 16, 2024 · The neighboring lines are about 0.01 nm from each other, making them ideal for monitoring background molecular absorption and scatter. Corrections using the Zeeman Effect are more reliable than those using a continuum source. The magnetic field can be applied either to the hollow cathode lamp or the atomization source.

Aspects of deuterium lamp operation for background correction are also covered. 2 Gas Fill The filler gas must be monatomic in order to avoid molecular continuum spectra and thus it must be an inert, noble gas. The filler gas is usually argon or neon, … WebDeuterium background correction is the oldest and still most commonly used technique, particularly in flame AAS. In this technique, a separate source (deuterium lamp) with broad emission is used to measure background absorption over the entire width of the exit slit of the spectrometer. The use of a separate lamp makes this technique the least ...
