The sensitivity determination of energetic materials from laser spark spectrometry based on physical-parameter-corrected statistical methods

Journal of Analytical Atomic Spectrometry, 2021
A simple method combining the impact of various factors on sensitivity is developed to determine various sensitivities via laser spark spectrometry with the consumption of only several milligrams of EM, rather than via macro-detonation testing.

Characterization of an Airborne Laser-Spark Ion Source for Ambient Mass Spectrometry

Analytical Chemistry, 2017
An airborne laser plasma is suggested as an ambient ion source for mass spectrometry. Its fundamental physical properties, such as an excellent spatial and temporal definition, high electron and ion densities and a high effective cross section in maintaining the plasma, make it a promising candidate for future applications. For deeper insights into the

Factors affecting the relative sensitivity coefficients in spark and laser plasma source mass spectrometry

International Journal of Mass Spectrometry and Ion Processes, 1985
Abstract Any a priori calculations of relative sensitivity coefficients (RSC) using empirical formulae which take into account only the analyte properties are shown to be fruitless. In a series of experiments with model samples, it has been possible to determine the contribution of each individual step of mass spectrum formation, viz.

Perspectives in the development of the theory of spark-source and laser-plasma source mass-spectrometry

Talanta, 1987
The processes of substance evaporation and atom ionization under different conditions of spark discharge or laser radiation are considered. It is shown that the dependence of the relative sensitivity coefficients on the properties of an element can be presented as the product of two exponents with parameters proportional to the atomization energies and

Application of vacuum ultraviolet laser-induced breakdown spectrometry for steel analysis — comparison with spark-optical emission spectrometry figures of merit

Spectrochimica Acta Part B: Atomic Spectroscopy, 2001
Abstract Laser induced breakdown spectrometry (LIBS) was evaluated for trace analysis in steel in comparison to spark discharge optical emission spectrometry (spark-OES), including low C, N and S (
