Using qualifier ions to improve ICP-MS data quality for waste water analysis
نویسنده
چکیده
Researchers at a commercial environmental laboratory have developed an effective method for validating high throughput multi-element data from high matrix waste water samples. The method used an Agilent 7700x ICP-MS with High Matrix Introduction (HMI)1 capability and third generation Collision Reaction Cell (CRC) operating in helium (He) mode. This simultaneously removes the polyatomic interferences from all isotopes of each analyte and gives access to secondary isotopes for many analytes. Simply checking the agreement between the results from the primary and secondary isotope provides a quick and easy means to confirm the accuracy of the analytical data. The new method was validated by analyzing approximately 6000 samples over a 21-week study period. Using qualifier ions to improve ICP-MS data quality for waste water analysis
