Collisional radiative model for high-ionization-rate equilibrium argon plasma plume

Atomic spectrometry update: review of advances in atomic spectrometry and related techniques

“…Mo isotopes were measured on low-concentration samples (∼5 ng g −1 ) by Zhu et al 194 They used a 97 Mo- 100 Mo double spike added to sample solutions prior to Mo isolation and measurement using MC-ICP-MS. Results for d 98 Mo/ 95 Mo were reproducible to ±0.03&.…”

“…A collisional radiative (CR) model for a neutral and singly ionised Ar plasma was developed by Han et al 95 The plasma in question was a 15 kW applied-field magnetoplasmadynamic thruster so it is debatable how relevant it is to analytical atomic spectrometry. They used 31 Ar I and 95 Ar II levels to build the model, taking into account radiative decay, electron impact ionisation, excitation and de-excitation, fast ion and atom impact excitation, and three body recombination.…”

Helium line emission spectroscopy to measure plasma parameters using modeling and machine learning in low-temperature plasmas

“…Based on CR model calculations, line intensity ratios (LIRs) have long been utilized to determine n e and T e . Argon (Ar) gas is commonly used in nonfusion low-temperature plasmas, and Ar I CR models have been developed to gain insight into Ar plasmas [38][39][40][41][42][43][44][45][46][47]. For instance, six pairs of Ar I LIRs were examined for the determination of n e and T e in comparison with those measured using a double probe as a function of the RF input power in helicon discharge plasmas [44].…”
