Periodic Table of TMI-OES Standards This standard scheme is used for ICP-OES using 2 calibration curves.

What IV does on the MS

• Standard Additions Method • Dilute sample to 100ppm of the major element • Spike half of that sample with 4ppb of standard • 3 Blanks → Sample → Sample+Spike → 3 Blanks • We use 3 times the standard deviation for LOD • Not utilizing spectra but do evaluate washout • Easier to automate the process
