Atomic Emission Spectroscopy: Interference

Atomic Emission Spectroscopy: Interference

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: Atomization Methods

Atomic Absorption Spectroscopy (AAS) atomizes samples through flame atomization or electrothermal atomization. Flame atomization typically involves a nebulizer and spray chamber assembly to combine the sample with a fuel–oxidant mixture, creating a fine aerosol mist that enters a burner. Typically, the fuel and oxidant are combined in an approximately stoichiometric ratio. However, for atoms that are easily oxidized, a fuel-rich mixture may be more advantageous. Only about 5% of the...

Atomic Emission Spectroscopy: Lab

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...

Summary

Acoustic models for gas bubbles are inaccurate for larger bubble sizes (ka > 0.5). This study shows that non-spherical bubble shape, size, and orientation cause significant variability in acoustic backscattering cross section measurements.

Area of Science:

Fluid dynamics
Acoustics
Bubble dynamics

Background:

Gas bubbles in liquids are crucial in various research fields.
Acoustic inversion techniques are used to determine bubble properties.
Existing acoustic models often assume spherical bubbles and small size relative to wavelength (ka ≪ 1).

Purpose of the Study:

To investigate the impact of non-spherical shapes on acoustic backscattering cross section (σbs).
To evaluate the validity of common analytical models for non-spherical bubbles across a range of ka values.

Main Methods:

Experimental measurement of σbs for non-spherical gas bubbles.
Comparison of experimental data with four established analytical σbs models.
Analysis of bubble size, shape, and orientation effects on acoustic scattering.

Main Results:

All tested models accurately predicted σbs for ka < 0.5.
No single model consistently outperformed others for ka > 0.5.
Significant variability in experimental σbs for ka > 0.5 was observed, linked to bubble shape, size, and orientation.

Conclusions:

Current analytical models are insufficient for accurately predicting acoustic backscattering of non-spherical bubbles at higher ka values.
Bubble shape, size, and orientation are critical factors influencing acoustic scattering.
Further research is needed to develop more robust models for non-spherical bubble acoustics.
