پایداری کالیبراسیون جرمی اسپکترومتر ICP-MS دست دو
|
Measured using a 1 µg/L multielement solution containing 7Li, 24Mg, 115In and 238U. Defined in terms of the shift in spectral
position corresponding to maximum spectral peak intensity for each element, obtained without the use of multiple-point, peak-searching algorithms.
