A Survey of Basic Instrument Components Used in Spectroscopy, Part 3: Atomic Spectroscopy

In this Part 3 survey article of atomic spectroscopy instrument components, we look at instrument components and subassemblies used for the special components and terms used in atomic spectroscopy instrumentation for inductively coupled plasma–mass spectrometry (ICP-MS), ICP–optical emission spectrometry (ICP-OES), X-ray fluorescence (XRF), energy-dispersive X-ray spectroscopy (EDX), total reflection X-ray fluorescence (TXRF), and laser-induced breakdown spectroscopy (LIBS). Our “under the hood” look continues as we survey the most typical atomic spectroscopy design components. As we continue publishing our four-part component survey series, we note that tutorial articles, and The Spectroscopy Instrument Components Terminology Guide, posted digitally in February 2022, are available to our readers.

In this part 3 of our four-part spectroscopy components survey article, we take a closer look at the special components and terms used in atomic spectroscopy instrumentation for inductively coupled plasma–mass spectrometry (ICP-MS), ICP–optical emission spectrometry (ICP-OES), X-ray fluorescence (XRF), energy-dispersive X-ray spectroscopy (EDX), total reflection X-ray fluorescence (TXRF), and laser-induced breakdown spectroscopy (LIBS). The various instrument acronyms are defined within the table. The atomic spectroscopy techniques and components are described in Table IV, with the table containing four columns of information—the technique or component name, a text description, basic specifications, and references and links (1–4). All topics are in alphabetical order for this table. The list of basic techniques and components used for atomic spectroscopy instrumentation is obviously a very large subject with many details. Here, we are taking a broad look to survey the main techniques or components used for atomic spectroscopy instruments. More topic details are included within The Spectroscopy Instrument Components Terminology Guide, which is available online (1).

As with other analytical instruments, atomic spectroscopy instrumentation is advancing rapidly because of discovery research, new materials, improved mechanical tolerances, and continuous developments in electronics, algorithms, and computational power.
