일반 설명

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

애플리케이션

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]

The analysis of amino acids by gas chromatography mass spectrometry (GC-MS) after their derivatization with N-(t-butyldimethylsilyl)-N-methyltrifluoroacetamide was investigated as an alternative approach for the determination of free (FAA) and combined amino acids (CAA) in aerosols. This technique showed excellent linearity
