“…Hence, careful control of the temperature program and modification of the matrix allows the removal of interferences. In situ speciation analysis can even be performed if different chemical forms of an element have sufficiently different volatilities Willie, Grégoire, & Sturgeon, 1997). ETV can also be combined to vapor generation, where the vapor is collected and accumulated in the ETV before being vaporized into the ICP, hence achieving not only a separation from the matrix but also a substantial in situ preconcentration, while eliminating the hydrogen byproduct of HG.…”

This article reviews the numerous ways in which inductively coupled plasma mass spectrometry has been used for the analysis of environmental samples since it was commercially introduced in 1983. Its multielemental isotopic capability, high sensitivity and wide linear dynamic range makes it ideally suited for environmental analysis. Provided that some care is taken during sample preparation and that appropriate calibration strategies are used to circumvent non-spectroscopic interferences, the technique is readily applicable to the analysis of a wide variety of environmental samples (natural waters, soils, rocks, sediments, vegetation, etc.), using quadrupole, time-of-flight or double-focusing sector-field mass spectrometers. In cases where spectroscopic interferences arising from the sample matrix cannot be resolved, then separation methods can be implemented either on-or off-line, which can simultaneously allow analyte preconcentration, thus further decreasing the already low detection limits that are achievable. In most cases, the blank, prepared by following the same steps as for the sample but without the sample, limits the ultimate detection limits that can be reached.

“…These solutions were prepared just before measurement. It was necessary to have two calibration curves, since sensitivities are different for aqueous standards with and without the addition of KMnO 4 . In this sense, for the determination of inorganic mercury, 3.0 mL of the standard solution in 5.0% v/v HNO 3 was used.…”

A simple, fast and reliable method for the determination of inorganic and total mercury in biological samples directly from slurries prepared in water has been developed using cold vapor atomic absorption spectrometry. The method does not require any standing time or heating of the slurries. Samples are simply mixed with water and measurement can be carried out immediately. For inorganic mercury determination, no additional preparation is required. For total mercury determination the samples have to be oxidized previously with a 2% m/v KMnO 4 solution for 2 minutes. After that, the measurement can be carried out similarly to that for inorganic mercury determination. The methylmercury concentration can be calculated as the difference between total and inorganic mercury. The greatest advantage of this method is that only a minimum of reagents and sample handling steps are required, which stands as a prerequisite for accurate results in routine analysis, particularly for the determination of mercury. The results were in good agreement with the 95% confidence level of the certified or close to the informed value for the reference materials investigated. The relative standard deviation was better than 7% for most of the samples. The limits of detection in the sample were determined as 0.020 and 0.016 mg g À1 for inorganic and total mercury, respectively.

“…However, the Electrothermal vaporization (ETV ) is one of the sample isotope dilution method cannot be used for mono-isotopic introduction techniques that is currently employed in elements. Furthermore, the isotopes chosen must be free from ICP-MS. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] This alternative technique to solution nebulizisobaric and polyatomic interferences.
