High-Throughput Semiquantitative Screening of Ambient Air Samples by ORS-ICP-MS and Integrated Sample Introduction System (ISIS) Application
ثبت نشده
چکیده
A new method has been developed to analyze large numbers of air samples for trace metal content. To aid sample throughput, an Agilent Integrated Sample Introduction System (ISIS) was used with an Agilent 7500c Octopole Reaction System-ICP-MS operating in semiquantitative analysis mode. Using this methodology, 2,500 samples were analyzed for dissolved and extractable elemental composition in approximately 2 weeks. Instrument stability and reliability was demonstrated by good recoveries for the NIST 1643e water CRM. Data handling made use of macros to download and export sample results in a format easily imported by statistical analysis software.

Determination of Mercury in Microwave Digests of Foodstuffs by ICP-MS Application
The quantitative determination of mercury in foodstuffs is presented using a 7500i ICP-MS. Microwave digests were prepared and then analyzed by ICP-MS. To avoid memory effects often experienced with mercury, gold was added offline to all standards/samples and wash solutions to act as a cleansing agent. The instrumental setup used a second vacuum pump, the integrated sample introduction system i...
متن کاملThe ultratrace determination of iodine 129 in aqueous samples using the 7700x ICP-MS with oxygen reaction mode
Determination of the radionuclide iodine 129 using ICP-MS has been improved by the use of an Octopole Reaction System (ORS) ICP-MS, operated in oxygen cell mode. Oxygen reaction gas removes the background signal at m/z 129, which is due to the presence of Xe as an impurity in the Ar plasma gas and to the polyatomic ion IH2. NIST SRM standards with different 129I/127I ratios and at multiple conc...
