Hello! This is my first thread and its about the use of a hyphen.
I write for a scientific company and my question is this.
The engineers I write for can use either one of two different solvent grades for their tests, acetonitrile HPLC grade or MS grade.
So if I write:
Acetonitrile, HPLC or MS-reagent-grade,
...have I made correct use of the hyphen?
Thanks for any advice.
