Quantitative ion probe analysis of glasses by empirical calibration methods

Abstract

technique for quantitative analysis for trace amounts of arsenic. Comparison of detection limits (Table III) demonstrates that the ESCA-volatilization technique is quite competitive with other trace analytical methods. Likewise, our analytical method shows both good accuracy and precision.Further, volatilization can be performed in the field making remote sampling facile. The possibility of doing quantitative simultaneous multielement analysis at trace levels also has been demonstrated. ACKNOWLEDGMENTThe authors express their gratitude to F. W. Plankey and E. M. Heithmar for loan of the atomic absorption standards and for some helpful discussions; also to S. Erickson for her assistance. LITERATURE CITED(1) T. A.

Relative sensitivity factors of elements in quantitative secondary ion mass spectrometric analysis of biological reference materials

“…Error factors have previously been used to compare RSF quantification of glass (2,5,6) and metallurgical (6, 7) matrices. Error factors are defined as the determined concentration divided by the true concentration.…”

“…Due to the low melting point, aprotic, and relatively anhydrous nature of the AlCl3BuPyCl melts, they have been employed as solvents for electrochemical and spectroscopic investigations of both organic and inorganic species (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13).…”

Direct digitization system for quantification in ion microscopy

“…Previous attempts to quantify nonimaging SIMS data have been pursued by one of two general methods: the application of theoretical ionization models such as the local thermal equilibrium (LTE) model originated by Andersen and Hinthorne ( 16) or empirical methods such as the use of relative sensitivity factors (17). Several attempts to quantify ion images using theoretical models have been reported by using LTE correction (18), sensitivity factor correction (17), total current monitoring (19), and application of simple correction factors (20).…”

Digital image processing for image quantification in ion microscope analysis

“…Despite the problems there have been many attempts to quantify nonimaging SIMS, with varying degrees of success. Two of the most popular methods have been empirical approaches such as the use of relative sensitivity factors (10) and the application of theoretical ionization models such as the local thermal equilibrium (LTE) model originated by Andersen and Hinthorne (11). There have also been ion image quantification attempts, although they are much fewer in number.…”
