说明

一般說明

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

應用

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.
• 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.
• Preparation of tryptic digests from the standard protein samples and milk digests from milk samples.
• Preparation of C₆₀-aminopropylsilica.
