High-resolution continuum-source electrothermal atomic absorption spectrometer for simultaneous multi-element determination in the spectral range of 190–780 nm

Abstract

We have built a prototype atomic absorption spectrometer with an electrothermal atomizer and continuum light source for simultaneous multi-element determination.

Breaking the boundaries in spectrometry. Molecular analysis with atomic spectrometric techniques

“…That may change in the future, as it is technically possible to improve this aspect substantially without losing resolution, and the use of a prototype with drastically improved capabilities has already been reported by Geisler et al [73]. Also, Labusov et al have presented another prototype with a much wider spectral window (190-780 nm), although with a resolution of only 10 to 30 pm [74].…”

“…In the case of the optical techniques, what can be expected in the future is to make more use of the potential to combine molecular and atomic spectra. In the case of MAS, this requires the use of instrumentation with much wider spectral windows, which is already technically possible, as clearly demonstrated by Geisler et al [73] and Labusov et al [74]. In the case of LIBS, this is also possible, but there is another interesting trend to consider: combining both LIBS/LAMIS and LA-ICP-MS(/MS) information from the same ablation process [148].…”

Optical Design of an Integrated Paschen–Runge Spectrometer by Using a Multigrating Structure

“…Then, in the 1940s, the first direct-reading spectrometer was developed and has been deeply researched and applied in many directions [3]. The traditional direct-reading spectrometer usually adopts the Paschen-Runge structure; the main components are concave grating with large curvature and a large amount of groove density, and multiple detectors are distributed on the Rowland circle [4][5][6]. In order to achieve high-resolution and wide waveband detection, long focal lengths and multiple linear detectors are usually used, resulting in a larger volume of the direct-reading spectrometer, which is inconvenient for on-site detection.…”
