| 中文摘要 | the present paper deals with the evaluation of the relative error (delta(a)) in estimated analyte concentrations originating from the wavelength positioning error in a sample scan when multicomponent analysis (mca) techniques are used for correcting line interferences in inductively coupled plasma atomic emission spectrometry. in the theoretical part, a quantitative relation of delta(a) with the extent of line overlap, bandwidth and the magnitude of the positioning error is developed under the assumption of gaussian line profiles. the measurements of eleven samples covering various typical line interferences showed that the calculated delta(a) generally agrees well with the experimental one. an expression of the true detection limit associated with mca techniques was thus formulated. with mca techniques, the determination of the analyte and interferent concentrations depend on each other while with conventional correction techniques, such as the three-point method, the estimate of interfering signals is independent of the analyte signals. therefore. a given positioning error results in a larger delta(a) and hence a higher true detection limit in the case of mca techniques than that in the case of conventional correction methods. although the latter could be a reasonable approximation of the former when the peak distance expressed in the effective width of the interfering line is larger than 0.4. in the light of the effect of wavelength positioning errors, mca techniques have no advantages over conventional correction methods unless the former can bring an essential reduction ot the positioning error. |
