Atomic absorption spectrometer and high-pressure lamp for continuous atom absorption spectroscopy - includes high pressure lamp emitting continuous spectrum and optical system for producing measurement light beam emanating from high pressure lamp

摘要

The spectrometer also contains an atomising unit (18) for atomising a sample to be tested. Such that the elements to be determined in an atomising region penetrated by the measurement light beam (14), exist in atomic form. A high resolving dispersion system (30) is provided for the spectral splitting up of the light beam (14), and a detector system (40) with a number of detector elements is acted on with the spectrally split measurement light beam (14). The high-pressure (HP) lamp (10) is doped with at least one element, such as arsenic or selenium. USE/ADVANTAGE - Continuous spectrum atomic absorption spectroscopy (CSAAS). Spectrometer with continuous spectrum HP lamp e.g. xenon (HP) lamp. Improves signal-to-noise ratio and compensation for background absorption.
