| 中文摘要 | the present paper reports some definite evidence for the significance of wavelength positioning accuracy in multicomponent analysis techniques for the correction of line interferences in inductively coupled plasma atomic emission spectrometry (icp-aes). using scanning spectrometers commercially available today, a large relative error, delta(a) may occur in the estimated analyte concentration, owing to wavelength positioning errors, unless a procedure for data processing can eliminate the problem of optical instability. the emphasis is on the effect of the positioning error (deltalambda) in a model scan, which is evaluated theoretically and determined experimentally. a quantitative relation between delta(a) and deltalambda, the peak distance, and the effective widths of the analysis and interfering lines is established under the assumption of gaussian line profiles. the agreement between calculated and experimental delta(a) is also illustrated. the delta(a) originating from deltalambda is independent of the net analyte/interferent signal ratio; this contrasts with the situation for the positioning error (dlambda) in a sample scan, where delta(a) decreases with an increase in the ratio. compared with dlambda, the effect of deltalambda is generally less significant. |
