Observation of line shifts and line profiles in an inductively coupled argon plasma

Enclosed Inductively Coupled Plasma: Spatially Resolved Profiles of Rotational Temperatures and Analyte Atom Distribution

“…These limitations of a ow-through system can theoretically be overcom e by an enclosed ICP. A low pressure, non-owing, rf-powered plasma cell was described by Manning et al 8,9 and used for spectroscopic studies of noble gases, oxygen, carbon dioxide, and ethylene. The cell was not suitable for operation at atmospheric pressures or higher, or with toxic resp.…”

Stark broadening of Ba I and Ba II spectral lines

“…Kato et al (1984) investigated wavelength shifts of Ba I and Ba II lines emitted by an inductively coupled plasma. Manning et al (1990) performed a study of the effect of pressure and electron density on wavenumber position for Ba II lines. Experimental Stark broadening parameters for ionized barium lines of Jaeger (1969), obtained with the help of a discharge sliding along the surface of a liquid jet, Purić & Konjević (1972), where the plasma source was a T-tube, Tables 1 and 2 are only available in electronic form: see the Editorial in A&AS 1994, Vol.…”

Combining single-element stored spectra for the simulation of experimental spectra using multichannel detection-based ICP-AES

“…The various gas flows were adjusted by means of mass flow controllers. The plasma gas, the auxiliary gas and the carrier gas flow rates were set-up at 14, 1 and 0.9 l min 21 , respectively. The choice of the power and carrier gas flow rate values will be justified below.…”

“…The CISRI 312 stainless steel reference material (China Scientific Instruments & Materials Corporation, Beijing) with 18.6% of Cr, 8.83% of Ni, 2.9% of Cu, and 0.07% of Co, was used to provide the experimental spectrum. Spectra acquisition was performed with single-element solutions at a concentration of 100 mg L 21 , and with the reference material solution with a salt concentration of 10 g L 21 after dissolution of steel in HCl. Water with the same HCl concentration was used for the so-called water spectrum.…”

“…Besides line assignment, it would be of interest to have knowledge of line properties such as the excitation energy, the transition probability, the a-value used in the calculation of the Voigt profile 18,19 and possible line shifts. [20][21][22] This would then permit the computation of synthetic spectra to facilitate line selection. [23][24][25][26][27] The excitation energy is known for most of the lines available in wavelength tables.…”
