چکیده
Selenium (Se) is an important element in environmental and agricultural studies and in human health, as it is an essential trace nutrient but is also toxic in excess. The role of certain chemical forms of Se is also the subject of signifi cant research into cancer prevention. ICP-MS is the analytical method of choice for both total and speciated Se measurements, but Se is diffi cult to quantify accurately at trace levels by ICP-MS for several reasons:

Agilent 8800 Triple Quadrupole ICP-MS: Understanding oxygen reaction mode in ICP-MS/MS
The use of oxygen as a reaction gas for the removal of interferences in quadrupole ICP-MS is well established. However, prior to the development of the Agilent 8800 Triple Quadrupole ICP-MS (ICP-QQQ), the use of oxygen had been limited to determination of a small number of analytes in simple, well defined matrices. This is because oxygen can react with matrix components, analytes and polyatomic...

A new method is described for the accurate determination of silicon (Si), phosphorus (P), and sulfur (S) in lubricating oil samples using an Agilent 8800 Triple Quadrupole ICP-MS (ICP-QQQ). An optimized oxygen (O2) massshift method provided limits of detection for 28Si, 31P, 32S and 34S of 0.25, 0.01, 0.18 and 0.75 ppb, respectively. The method was successfully applied to the determination of S...
