摘要:Abstract(#br)In the analysis of arsenic (As) with ICP-MS, it was observed that methanol addition to the sample decreases the amount of 40 Ar 35 Cl + formed in the previous study. To investigate the effect of methanol addition on generation of isobaric polyatomic ions and its mech...

摘要:Abstract(#br)Feasibility of collision cell (CC) technique with the aid of a methanol modifier for the trace determination of arsenic (As) in a high-chloride-containing sample using ICP-MS was assessed to eliminate the analytical bias induced by polyatomic interference from 40 Ar ...

摘要:... The reagents for 50-mg coal sample digestion are 2-ml 40% (v/v) HF and 5-ml 65% (v/v) HNO 3 but for the CCP samples, the reagents include 5-ml 40% HF and 2-ml 65% HNO 3 . To significantly diminish the argon-based interferences at mass to charge ratios ( m / z ) 75 ( 40 Ar 35 ...

摘要:... The formation of the polyatomic interference ion, 40 Ar 35 Cl + , hampers the determination of arsenic even when the interference equation is employed. The interference of 40 Ar 35 Cl + can be accurately corrected only at minimum chlorine concentration (<500 ppm). The concent...

摘要:... High-chlorine content samples are also challenging for As and Cr determination due to the formation of polyatomic species such as 40 Ar 35 Cl + and 35 Cl 16 OH + , which overlap the only As isotope, 75 As + , and the main Cr isotope, 52 Cr + , respectively. The combination...

摘要:... The formic acid causes a slight decrease of the analytes signal intensities, but does not increase the signal of the mainly polyatomic ions ( 14 N 35 Cl + , 14 N 12 C + , 40 Ar 12 C + , 13 C 37 Cl + , 40 Ar 36 Ar + , 40 Ar 35 Cl + , 35 Cl 16 O + , 40 Ar 18 O + ) that affec...

摘要:... Addition of 3 mL min −1 methane to Ar-plasma eliminates the signal suppressions of various elements (As, Se, Hg, etc.) due to the high concentration of nitric acid (10%, v/v). The CH 4 –Ar mixed plasma may compensate for the plasma cooling effects due to the highly co...

摘要:... An empirically derived equation relating the measurement of 16 O 35 Cl to the 40 Ar 35 Cl contribution to the arsenic signal at mass 75 is refined by measuring the responses at mass 51 and 75 for urines with added hydrochloric acid. Overall, ICP-MS results for blood and urine...

摘要:... 40 Ar 35 Cl + vs. 75 As + ) obtained for ETV sample introduction when compared to the conventional system. Finally, no differences for Pb determination were observed between ETV sample introduction and ETAAS. Unfortunately, the limits of detection for As and Se in ETAAS were ...

摘要:... The interference of 40 Ar 35 Cl + at arsenic mass m / z 75 was reduced significantly using dynamic reaction cell (DRC). Standard addition and isotope dilution methods were used for the quantifications. The method reported has been applied to the determination of Cu, As, ...
