“…Fig.1 shows the effects of 40 Ar 16 O peak on 56 Fe in the high purity gallium at m/Δ m＝8000. The result suggests that MRM would cause a part of 40 Ar 16 O peak doubled with 56 Fe peak and interfered seriously, and that through HRM the interferences of 40 Ar 16 O peak effectively disappear. Fig.2 shows the interferences of 40 Ar 35 Cl peak to 75 As peak at m/Δ m＝8000.…”

Trace elements were determined in high purity gold by high resolution inductively coupled plasma mass spectrometry (HR-ICP-MS). Sample were decomposed by aqua regia. To overcome some potentially problematic spectral interference, measurements were acquired in both medium and high resolution modes. The matrix effects due to the presence of excessive HCl and Au were evaluated. The optimum conditions for the determination was tested and discussed. The standard addition method was employed for quantitative analysis. The detection limits range from 0.01μg/g to 0.28μg/g depending on the elements. The method is accurate, quick and convenient. It has been applied to the determination of trace elements in high purity gold with satisfactory results.

Nevertheless, quantification of chromium in matrix-loaded sample solutions was readily possible because of the highly reproducible recovery values obtained [16] .…”

For the analysis of cadmium, the toxicity of spectroscopic methods is increasing because the measurement of the low level for detection of this element is done in various samples. This review studies the methods of separation and pre-concentration and analyzes spectroscopic methods for detecting cadmium in water samples. Considering the amount of trace cadmium ion in the analysis of aqueous samples, a suitable method should be used. From the past, chemists have been trying to find a solid phase to recover analytes from the water matrix. The experimental method of SPE is a standard method for the analysis of heavy metals such as cadmium ion in aqueous samples. Cadmium is known worldwide as a toxic metal. Therefore, it is often necessary to determine this element in environmental, biological, food and agricultural samples. However, analyses are difficult because the quantities of cadmium samples are relatively small, except for trace amounts. Measurements are made by flame atomic absorption spectrometry and inductively coupled plasma optical emission spectrometry.For this reason, several preconcentration methods for the determination of cadmium ion, including solid phase extraction, coprecipitation and cloud point extraction, has been reviewed.A brief history of using Solid-phase extraction in the analysis of cadmium ion in water samples is presented in this paper.
