    Hyphen use

    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.
    L.

    You say that they can use two solvents: acetonitrile HPLC grade or MS grade. These seem fine as they are.

    Why have you inserted a comma or hyphens?
