What is the Reason if the RSD is Bad?
2 month ago, the RSD was under 5% . Today the RSD is up to 20% especilly for Boron. Tubes Changed 4 weeks ago.
Is this for an ICP-MS? What model ICP-MS do you have? What kind of samples are you analyzing? What is the Boron concentration in your samples?
It is an ICP-MS 7800 from 2018. Most of the Samples are drink water and fountain water. The Boron concentration
is up to 5ppm.
The boron has a memory effect from such a high concentration of standard at 5ppm. Do you need to calibrate so high?
