↵Notes: 1Stabilization of sample matrix in sample introduction and stabilization in plasma without fast pump flow rate to speed the uptake of the sample into the sample introduction.
↵2 Rinse time is based on washout of the highest concentration of elements to eliminate carryover. Sodium and phosphorous buffer samples required longer rinse time than pure water samples.
↵3 Per manufacturer's specifications.
