Using Qualifier Ions to Improve ICP-MS Data Quality for Waste Water Analysis
17 Sep 2014

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 uses an Agilent 7700x ICP-MS with High Matrix Introduction (HMI)1 capability and third generation Collision Reaction Cell (CRC) operating in helium (He) mode to simultaneously remove the polyatomic interferences from all isotopes of each analyte. This gives access to secondary isotopes for many analytes, and 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.
