Two standard reference materials (NIST 1632a and 1632b) were used to evaluate the accuracy in the determination of As, Hg and Se in coal by flow injection (FI) hydride-generation (HG) AAS and FI HG ICP-MS after microwave solubilization (Anal. Chim. Acta, 1989, 225, 159). RSD over 2 years were 10% for As, 8.11% for Se and 15% for Hg. The use of real fuel oil samples to compare results obtained for the determination of Ni and V by NAA, ICP-MS, ETAAS and ICP-AES in 54 laboratories is discussed. Similarly, the use of real samples to detect significant bias in the determination of As, Hg and Se in coal using various techniques (NAA, FI HG AAS, FI HG ICP-MS, ETAAS) is discussed.',

			'abstract' => 'Mercury was determined by isotope dilution cold-vapor inductively coupled plasma mass spectrometry (ID-CV-ICP-MS) in four different liquid petroleum SRMs. Samples of approximately 0.3 g were spiked with stable (201)Hg and wet ashed in a closed system (Carius tube) using 6 g of high-purity nitric acid. Three different types of commercial oils were measured: two Texas crude oils, SRM 2721 (41.7&plusmn;5.7 pg g-1) and SRM 2722 (129&plusmn;13 pg g-1), a low-sulfur diesel fuel, SRM 2724b (34&plusmn;26 pg g-1), and a low-sulfur residual fuel oil, SRM 1619b (3.5&plusmn;0.74 ng g-1) (mean value and 95% CI). The Hg values for the crude oils and the diesel fuel are the lowest values ever reported for these matrices. The method detection limit, which is ultimately limited by method blank uncertainty, is approximately 10 pg g-1 for a 0.3 g sample. Accurate Hg measurements in petroleum products are needed to assess the contribution to the global Hg cycle and may be needed in the near future to comply with reporting regulations for toxic elements.',

Abstract: An isotope dilution cold vapor inductively coupled plasma mass spectrometry (ID-CV-ICPMS) method featuring gaseous introduction of mercury via tin chloride reduction has been developed and applied to the quantification and certification of mercury in various NIST standard reference materials: SRM 966 Toxic Metals in Bovine Blood (30 ng mL-1); SRM 1641d Mercury in Water (1.6 µg mL-1); and SRM 1946 Lake Superior Fish Tissue (436 ng g-1). Complementary mercury data were generated for SRMs and NIST quality control standards using cold vapor atomic absorption spectroscopy (CVAAS). Certification results for the determination of mercury in SRM 1641d using two independent methods (ID-CV-ICPMS and CVAAS) showed a degree of agreement of 0.3% between the methods. Gaseous introduction of mercury into the ICPMS resulted in a single isotope sensitivity of 2 x 10(6) counts s-1 ng-1 g for Hg-201 and significantly reduced the memory and washout effects traditionally encountered in solution nebulization ICPMS. Figures of merit for isotope ratio accuracy and precision were evaluated at dwell times of 10, 20, 40, 80, and 160 ms using SRM 3133 Mercury Spectrometric Solution. The optimum dwell time of 80 ms yielded a measured Hg-201/Hg-202 isotope ratio within 0.13% of the theoretical natural value and a measurement precision of 0.34%, on the basis of three replicate injections of SRM 3133.

Three different types of commercial oils were measured: two Texas crude oils, SRM 2721 (41.7&plusmn;5.7 pg g-1) and SRM 2722 (129&plusmn;13 pg g-1), a low-sulfur diesel fuel, SRM 2724b (34&plusmn;26 pg g-1), and a low-sulfur residual fuel oil, SRM 1619b (3.5&plusmn;0.74 ng g-1) (mean value and 95% CI). The Hg values for the crude oils and the diesel fuel are the lowest values ever reported for these matrices. The method detection limit, which is ultimately limited by method blank uncertainty, is approximately 10 pg g-1 for a 0.3 g sample. Accurate Hg measurements in petroleum products are needed to assess the contribution to the global Hg cycle and may be needed in the near future to comply with reporting regulations for toxic elements.',

Abstract: Quality control procedures used for the determination of trace elements in fuel oil and coal are described. Two standard reference materials (NIST 1632a and 1632b) were used to evaluate the accuracy in the determination of As, Hg and Se in coal by flow injection (FI) hydride-generation (HG) AAS and FI HG ICP-MS after microwave solubilization (Anal. Chim. Acta, 1989, 225, 159). RSD over 2 years were 10% for As, 8.11% for Se and 15% for Hg. The use of real fuel oil samples to compare results obtained for the determination of Ni and V by NAA, ICP-MS, ETAAS and ICP-AES in 54 laboratories is discussed. Similarly, the use of real samples to detect significant bias in the determination of As, Hg and Se in coal using various techniques (NAA, FI HG AAS, FI HG ICP-MS, ETAAS) is discussed.

Three different types of commercial oils were measured: two Texas crude oils, SRM 2721 (41.7&plusmn;5.7 pg g-1) and SRM 2722 (129&plusmn;13 pg g-1), a low-sulfur diesel fuel, SRM 2724b (34&plusmn;26 pg g-1), and a low-sulfur residual fuel oil, SRM 1619b (3.5&plusmn;0.74 ng g-1) (mean value and 95% CI). The Hg values for the crude oils and the diesel fuel are the lowest values ever reported for these matrices. The method detection limit, which is ultimately limited by method blank uncertainty, is approximately 10 pg g-1 for a 0.3 g sample. Accurate Hg measurements in petroleum products are needed to assess the contribution to the global Hg cycle and may be needed in the near future to comply with reporting regulations for toxic elements.',

Complementary mercury data were generated for SRMs and NIST quality control standards using cold vapor atomic absorption spectroscopy (CVAAS). Certification results for the determination of mercury in SRM 1641d using two independent methods (ID-CV-ICPMS and CVAAS) showed a degree of agreement of 0.3% between the methods. Gaseous introduction of mercury into the ICPMS resulted in a single isotope sensitivity of 2 x 10(6) counts s-1 ng-1 g for Hg-201 and significantly reduced the memory and washout effects traditionally encountered in solution nebulization ICPMS. Figures of merit for isotope ratio accuracy and precision were evaluated at dwell times of 10, 20, 40, 80, and 160 ms using SRM 3133 Mercury Spectrometric Solution. The optimum dwell time of 80 ms yielded a measured Hg-201/Hg-202 isotope ratio within 0.13% of the theoretical natural value and a measurement precision of 0.34%, on the basis of three replicate injections of SRM 3133.',

Abstract: Mercury was determined by isotope dilution cold-vapor inductively coupled plasma mass spectrometry (ID-CV-ICP-MS) in four different liquid petroleum SRMs. Samples of approximately 0.3 g were spiked with stable (201)Hg and wet ashed in a closed system (Carius tube) using 6 g of high-purity nitric acid. Three different types of commercial oils were measured: two Texas crude oils, SRM 2721 (41.7±5.7 pg g-1) and SRM 2722 (129±13 pg g-1), a low-sulfur diesel fuel, SRM 2724b (34±26 pg g-1), and a low-sulfur residual fuel oil, SRM 1619b (3.5±0.74 ng g-1) (mean value and 95% CI). The Hg values for the crude oils and the diesel fuel are the lowest values ever reported for these matrices. The method detection limit, which is ultimately limited by method blank uncertainty, is approximately 10 pg g-1 for a 0.3 g sample. Accurate Hg measurements in petroleum products are needed to assess the contribution to the global Hg cycle and may be needed in the near future to comply with reporting regulations for toxic elements.
