Sub-ppb detection limits for hydride gas contaminants using GC-ICP-QQQ
نویسنده
چکیده
Hydride gases, such as phosphine and arsine, are important contaminants in process chemicals used in both the petrochemical and semiconductor industries. For example, the presence of phosphine, arsine, hydrogen sulfide and carbonyl sulfide in polymer grade ethylene or propylene can have a deleterious effect on catalysts used in the production of polypropylene plastics. Accurate data on the concentrations of these contaminants at trace levels enables prediction of catalyst lifetime and minimizes production downtime.

Application of ICP-MS as a multi-element detector for sulfur and metal hydride impurities in hydrocarbon matrices.
Maturation of inductively coupled plasma-mass spectrometry (ICP-MS) in terms of size, reliability, and cost has had a significant impact on its consideration as a viable detector for gas chromatography. Its generally excellent sensitivity for those elements it can measure has been a contributing factor. A method for sulfur speciation in various hydrocarbon products is investigated, as well as s...
متن کاملDetermination of P , Si and S in acid digested lubricating oil using the Agilent 8800 Triple Quadrupole ICP - MS Application note
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...
