Determination of Chloride in Crude Oils Using an Agilent 8900 ICP-QQQ

MS/MS technology promises more consistent and reliable reaction gas methods to be used for difficult elements, such as chlorine in complex matrices, than single quadrupole ICP-MS. In this application note, Agilent outlines a method where a NIST trace element in fuel oil SRM and 12 crude oil samples were prepared for analysis using direct dilution. The petroleum crude samples were analyzed using Agilent’s 8900 ICP-QQQ and the results show the importance of fully solubilized samples when using direct dilution as the sample preparation technique.
