Nickel Issues ICP-MS 7800

Lines 3-5 (blank, blank, 1/100ppb) make me think there is a contamination issue.

Check the cps of Ni on those first 4 blanks. If you see a downward trend, that could be an indication of a Nickel contamination somewhere in the instrument that is washing out. If they are all relatively equal, the blank solution itself may be contaminated.
