Catalog excerpts

The NexION 300X ICP-MS is available in two configurations: single and dual channel. The following performance can be measured under a single set of optimized conditions for each mode. Detection limits Based on three times the standard deviation of the blank using three-second integration time and peak hopping at 1-point per mass. Element 9 Be 59 Co 115 In 238 U Oxide and doubly-charged species Measured without the use of a desolvation device such as a chilled spray chamber and under identical operating conditions used to achieve sensitivity and detection-limit specifications. CeO+/Ce+ Ce++/Ce+ Background signal Mass 220 Short-term precision Defined as the relative standard deviation (% RSD) for a 1-10 µg/L multielement solution, automatically cycling between cell and non-cell modes, using a 3-second integration time, without internal standardization. < 3% RSD

Long-term stability Relative stability after a one-hour warm-up period. Defined as the relative standard deviation of the mean signal for a 1-10 µg/L multielement solution, automatically cycling between cell and non-cell modes, measured once every 10 minutes, without internal standardization. < 4% RSD over 4 hours Isotope-ratio precision Defined for the isotope ratio of Ag/109Ag. Obtained using single-point peak hopping. < 0.08*% RSD (*or within a factor of two of the counting statistics limit) Mass calibration stability Measured using a 1 µg/L multielement solution containing 7Li, 24Mg,...
