    General description

    HPLC Plus grade water is useful for the UHPLC (Ultra-High Pressure Liquid Chromatography) gradient elution and HPLC studies.

    Application

    Water has been used in the following studies:
    • To prepare the diluted hydrochloric acid solutions required for the preparation of standard solutions of amino acid.[1]
    • In the sample extraction step during the gas chromatography mass spectrometric (GC-MS) analysis of free (FAA) and combined amino acids (CAA) in aerosol samples.[1]
    • Preparation of tryptic digests from the standard protein samples and milk digests from milk samples.[2]
    • Preparation of C60-aminopropylsilica.[2]
