Effects of matrix on spatial profiles of emission from an inductively coupled plasma

Elemental matrix effects in ICP-AES

“…Elements such as sodium, potassium and caesium lead to shifts in the spatial plasma non-homogeneous 92 distribution of the analyte emitting species. 18,47,84,[93][94][95] Therefore, the matrix effects studied in the present review have a marked spatial character. The axial and radial observation positions in the plasma influence their extent.…”

Generalized standard addition method for multicomponent instrument characterization and elimination of interferences in inductively coupled plasma spectroscopy

“…For 226Ra, the chemical techniques range from a minimum of steps involving inert degassing of the sample following 222Rn secular equilibrium (1, 2) to various sequential procedures to isolate and purify the radium by utilizing classical coprecipitation (3, 4 ) , complexing (3, [5][6][7][8][9], or ion exchange (10)(11)(12) which are dependent on the measurement technique to be employed and the sample media being processed. The 226Ra measurement techniques employed vary from a simple 22zRn measurement by scintillation chamber (1-3, 5 , 7, 9, 12-15) to more sophisticated instrumentation involving a spectrometry (10, I I ) , mathematical procedures related to gross a counting of coprecipitated fiial sample forms (8), and liquid scintillation techniques (16).…”

Toward a Fuller Understanding of Analytical Atomic Spectrometry

“…This behavior is consistent with what has been termed a lateral diffusion interference. 2,[34][35][36][37][38] In this hypothesized mechanism, addition of an interfering species causes earlier release of analyte atoms and ions from the volatilizing sample aerosol. In turn, this earlier release provides more time for vaporization and diffusion to occur at any particular point higher in the plasma.…”
