HI, EVERYONE.
I write here today, because I have a Problem, in one company they want to buy solvents for amino acids analysis, but they want to buy ACS grade, I say them that they need HPLC grade, and high quality reagent, so they request from me information that bear what I am saying, in this moment I am far away from my Contry (CR. that explain my bad english, :oops: ) so I need a place where talk about the impotance of use of high puryti solvent on HPLC system, I tried to finded, but I could not, and I know that is very important the use of solvent HPLC grade but my word is not enough, for they.
Thank you very much!

Just tell them to run their HPLC with ACS solvent and then compare it to a run with HPLC grade.....

This article from SGE briefly mentions the need for high purity solvents.

(BTW, I have no affiliation with SGE)

The Waters Care and Use manuals recommend the use of HPLC-grade solvents.
