    DESCRIPTION

    General description

    SupraSolv solvents for headspace gas chromatography are developed particularly for the analysis of residual
    solvents in drug substances, excipients and drug products according to ICH, Ph Eur and USP - SupraSolv headspace solvents are tested for all
    residual solvents defined by the ICH.

    Caution

    Supercools easily and remelts slowly at room temperature. Solidified product can be re-liquified by warming to room temperature without detriment to the product.
