Introduction
ICP-MS has become the technique of choice for the monitoring of drinking waters. The fast, multi-element capability allows large numbers of samples to be routinely analyzed. While the ability to accurately quantify from ultra-trace to major levels means toxic metals, minerals and other contaminants can be determined within a single measurement. The PlasmaQuant® MS offers fast, multielement and interference-free analysis although with one noticeable difference. Robust plasma conditions suitable for drinking water analysis are achieved with only 7.5L/min of plasma(coolant) gas. The integrated Collision Reaction Cell(iCRC) provides fast and effective removal of spectroscopic interferences using the optimum collision or reaction gas for the job. Allowing the lowest possible detection limits to be achieved for each element. The high pressure/low volume reaction zone also means switching between gas modes takes only seconds.


Instrumentation
A PlasmaQuant® MS with Cetac ASX-520 autosampler and ASXpress rapid sample introduction system was used for the analysis. The Aspect MS software allows automatic optimization of the ion optics, iCRC and plasma gas flows and offers comprehensive quality control protocols, developed to meet the requirements of important regulated methodology including USEPA 200.8.



Samples and Reagents
Calibration standards
Calibration solutions were prepared from high-purity, multi-element solutions in 1% HNO3 covering the concentration range from 0 to 100 μg/L for trace elements and 0 to 100mg/L for major elements.


Sample preparation
NIST Certified Reference Materials 1640; Trace Elements in Natural Water and 1643e; Trace Elements in Water were analyzed directly.


Internal standard
Internal standard contained 1μg/L of Sc, Rh, Ir in 1% HNO3 and was added online via the 3rd channel on the peristaltic pump.


Results and Discussion
Tables 3a and 3b list the average result of triplicate measurements of NIST Certified Reference Materials 1643e and 1640 Trace Elements in Water. Excellent recoveries were recorded and typically fell in the range of ±5%. Analysis times were less than 1.5 minutes per sample using three optimized gas modes: He, no-gas and H2. Stabilization time between gas modes was <5 seconds. Total argon consumption was 9.55L/min which is half the amount typically required on competitive ICP-MS instruments.





Conclusion
This work demonstrates that the PlasmaQuant® MS provides fast and accurate analysis for monitoring the quality of drinking water. The advancement of sample introduction accessories reduces analysis times to less than 1.5 minutes while iCRC technology eliminates problematic interferences quickly and without compromise. A new RF generator design provides robust plasma conditions with only half the argon gas typically required of competitive systems, greatly reducing operating costs and instrument downtime. The capability of the all-digital detector to measure all analyte concentrations from ultra-trace to majors levels in a single ‘pulse-counting’ mode is a major benefit in the analysis of waters. It eliminates the need for performing inaccurate analog measurements when measuring strong signals.
