Factorial optimization of data acquisition factors for lead isotope ratio determination by inductively coupled plasma mass spectrometry

Accurate and precise Pb isotope ratio measurements in environmental samples by MC-ICP-MS

“…This results in poor peak shape and consequently in less precise measurements than using multi-collector sector instruments [4]. Typically, precisions of around 0.1-1.0% are achieved [5,6], depending on the concentration or matrix and the 204 Pb isotope is seldom measured. However, isotopic ratios including the 204 Pb isotope are of crucial importance for source assessments.…”

Lead/Cadmium Contamination and Lead Isotopic Ratios in Vegetables Grown in Peri-Urban and Mining/Smelting Contaminated Sites in Nanjing, China

“…The limits of detection for Pb and Cd were 0.005 and 0.002 lg L -1 in the present study. Lead isotopic analyses were conducted using a Perkin-Elmer ICP-MS SCIEX Elan 9000 as already described in the literature (Quétel et al 1997;Bindler et al 2004;Godoy et al 2007). Precision and accuracy were verified using a standard reference material from the National Institute of Standards and Technology (SRM 981 common lead isotopic material).…”

Concentration‐Gradient‐Method for sulphur and strontium isotope ratio determination by quadrupole‐based inductively coupled plasma mass spectrometry in gypsum

“…Many groups have tried to characterise and improve the precision of isotope ratio determination with ICP‐QMS . For example, Monna et al described the optimum integration times of measured isotopes depending on their isotopic composition for lead (Pb) and strontium (Sr).…”

“…Many groups have tried to characterise and improve the precision of isotope ratio determination with ICP-QMS. [12][13][14][15][16][17][18] For example, Monna et al 12 described the optimum integration times of measured isotopes depending on their isotopic composition for lead (Pb) and strontium (Sr). Some approaches are based on changes in hardware such as that by Gray et al 13 (using a free expansion interface and a bonnet to shield the ICP from the surrounding atmosphere) or the development of new devices for special applications such as multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS).…”
