Inductively Coupled Plasma-Mass Spectrometry (ICP-MS): Interferences01:20

Inductively Coupled Plasma-Mass Spectrometry (ICP-MS): Interferences

326
Inductively coupled plasma–mass spectrometry (ICP–MS) is a highly selective and sensitive technique for accurate elemental analysis. Though the analysis of ICP–MS mass spectra is comparatively straightforward, it is affected by spectroscopic and non-spectroscopic interferences. Spectroscopic interferences arise when the plasma contains ionic species with an m/z value the same as the analyte ion. Spectroscopic interference can be categorized as isobaric, polyatomic ions, and...

Atomic Emission Spectroscopy: Interference01:30

Atomic Emission Spectroscopy: Interference

124
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 Absorption Spectroscopy: Interference

511
Interference leads to systematic error in atomic absorption (AA) measurements by enhancing or diminishing the analytical signal or the background. These interferences can be grouped into three main categories: spectral interference, chemical interference, and physical interference.
Spectral interference occurs when signals from other elements or molecules overlap with the analyte signal, falsely elevating or masking the analyte's absorbance. This interference can be corrected using Zeeman,...

Area of Science:

  • Nanotechnology
  • Plasmonics
  • Surface Science

Background:

  • Interferometric scattering (iSCAT) is vital for studying single plasmonic nanoparticles (NPs), especially when they are too small for conventional scattering detection.
  • The iSCAT signal combines NP scattering with reflected light interference, making it sensitive to substrate and environmental factors.
  • This sensitivity can lead to discrepancies between iSCAT and dark-field scattering spectra, even for larger NPs.

Purpose of the Study:

  • To investigate how environmental factors influence iSCAT spectra of gold NPs.
  • To understand and control the interplay between scattering and interference regimes in iSCAT.
  • To demonstrate a method for accurate kinetic analysis of NP morphological changes using iSCAT.

Main Methods:

  • Tuning iSCAT contrast by altering the refractive index of the embedding medium, substrate reflectivity, and NP size.
  • Comparing iSCAT spectra with dark-field scattering spectra.
  • Utilizing a dipole oscillator model to interpret spectral lineshapes.
  • Performing multi-wavelength iSCAT measurements during electrodissolution experiments.

Main Results:

  • iSCAT contrast spectra of gold NPs can be shifted between scattering- and interference-dominated regimes.
  • Interference effects in iSCAT can displace spectral features from the intrinsic plasmon resonance.
  • A dipole oscillator model successfully explains the observed iSCAT spectral characteristics.
  • Multi-wavelength iSCAT is necessary for accurate kinetic parameter extraction during NP morphological changes.

Conclusions:

  • The iSCAT technique's sensitivity to environmental conditions must be carefully managed for reliable NP analysis.
  • Understanding and controlling the interference contribution is crucial for interpreting iSCAT data.
  • Multi-wavelength iSCAT measurements are essential for quantitative studies of dynamic NP processes like electrodissolution.
