Atomic Emission Spectroscopy: Instrumentation01:22

Atomic Emission Spectroscopy: Instrumentation

1.1K
The instrumentation of atomic emission spectrometry (AES) involves various components, including atomization devices that convert samples into gas-phase atoms and ions. There are two main types of atomization devices: continuous and discrete atomizers.  Continuous atomizers, like plasmas and flames, introduce samples in a constant stream, while discrete atomizers inject individual samples using syringes or autosamplers. The most common discrete atomizer is the electrothermal atomizer.

Ionization Energy03:12

Ionization Energy

42.5K
The amount of energy required to remove the most loosely bound electron from a gaseous atom in its ground state is called its first ionization energy (IE1). The first ionization energy for an element, X, is the energy required to form a cation with 1+ charge:

Atomic Absorption Spectroscopy: Radiation and Light Sources01:13

Atomic Absorption Spectroscopy: Radiation and Light Sources

1.0K
Atomic absorption spectroscopy (AAS) relies on the Beer-Lambert law, which requires that the radiation source emits a narrow range of wavelengths to match the absorption characteristics of the analyte atom. The primary criteria for choosing an appropriate radiation source in AAS is to provide a precise and intense emission at specific wavelengths that will allow accurate detection of the analyte.
Two common narrow-range 'line' sources used in AAS are hollow-cathode lamps (HCLs) and...

Inductively Coupled Plasma–Mass Spectrometry (ICP–MS): Overview

1.6K
In inductively coupled plasma–mass spectrometry (ICP–MS), an inductively coupled plasma (ICP) torch is used as an atomizer and ionizer. Solid samples are dissolved and volatilized before being introduced into the high-temperature argon plasma, while solution samples are nebulized and passed through the high-temperature argon plasma. Plasma dissociates the analytes and ionizes their component atoms to form a mixture of positive ions and molecular species. The positive ions are then...

Atomic Emission Spectroscopy: Interference

540
In atomic emission spectroscopy (AES), high-temperature atomizers excite a broad range of elements and molecules that generate complex emissions from sources such as oxides, hydroxides, and flame combustion products in the flame or plasma. Several strategies can be employed to minimize spectral interferences caused by overlapping emission lines or bands. These include increasing instrument resolution, choosing alternative emission lines, optimally placing the detector in low-background regions,...

Atomic Emission Spectroscopy: Lab

503
AES is a powerful analytical technique, especially effective when used with plasma sources, producing abundant spectra in characteristic emission lines. The Inductively Coupled Plasma (ICP), in particular, yields superior quantitative analytical data due to its high stability, low noise, low background, and minimal interferences under optimal experimental conditions. However, newer air-operated microwave sources are emerging as promising alternatives that could be more cost-effective than...

Area of Science:

  • Particle Physics
  • Cosmology
  • Astrophysics

Background:

  • The nature of dark matter remains one of the most significant unsolved problems in physics.
  • Direct detection experiments aim to observe dark matter particles interacting with ordinary matter.

Purpose of the Study:

  • To constrain theoretical models of light dark matter using data from the XENON1T experiment.
  • To explore dark matter-electron scattering and axionlike particle interactions.

Main Methods:

  • Utilized ionization signals from the XENON1T detector with an effective exposure of (22±3) tonne day.
  • Applied strong event selections to mitigate backgrounds, bypassing the need for scintillation signals.

Main Results:

  • Achieved an unprecedentedly low background rate of <1 event/(tonne day keVee) above ~0.4 keVee.
  • Excluded new parameter space regions for various light dark matter models, including DM-nucleus scattering (3-6 GeV/c²), DM-electron scattering (>30 MeV/c²), and dark photon/axionlike particle absorption (0.186-1 keV/c²).

Conclusions:

  • While a definitive dark matter or coherent elastic neutrino-nucleus scattering (CEvNS) detection was not claimed due to unmodeled backgrounds, the results significantly constrain light dark matter scenarios.
  • The study demonstrates the power of deep underground experiments in probing novel dark matter candidates and interactions.
