Assuming DL and LOQ levels would not be overly compromised, is it possible to just dilute the higher concentrations down to (approximately) the lowest using purified water and then matrix match the standards from there?
In other words get everything to right around 2.14 mM ammonium acetate.

Subject: Ammonium Acetate Matrix Match
Hi List Members,
I am running an Aglient ICPMS 7500 and I understand I need to matrix match for my ammonium acetate samples (learned that the hard way). However, I am running into the issue that my samples vary in ammonium acetate concentrations. I needed to dilute up to have enough sample and so my ammonium acetate concentrations are around 2.14mM, 2.5mM, and 3.13mM. Any assistance would be greatly appreciated.
