The study analyzed arsenic, chromium, iron, copper, nickel, zinc, selenium, lead, cadmium, and thallium.
The instrument was operated in no-gas, helium, and hydrogen modes.
Two certified reference materials, LGC7160 and SRM1577b, were analyzed.
Recoveries were 100 +/- 15% of the certified value for all elements.
