Product Description

Detailed information about the product

Product Overview

Water For HPLC (CAS No. 7732-18-5) is high-purity water intended for liquid-chromatographic mobile phases, sample preparation and chromatographic reagent systems. In HPLC, water often constitutes the principal aqueous component of isocratic or gradient mobile phases, so particulate, ionic and organic contamination can influence baseline stability, retention, column cleanliness and detector response.

The HPLC grade is intended for chromatographic mobile phases, buffers, sample diluents, blanks and extraction solutions. Its chromatographic role centres on maintaining a clean aqueous solvent background during isocratic and gradient HPLC procedures.

Typical Applications

  • Aqueous component of HPLC mobile phases.
  • Preparation of HPLC buffers and reagent solutions.
  • Chromatographic sample dilution.
  • Preparation of HPLC blanks.
  • Extraction and sample preparation before liquid chromatography.
  • Routine isocratic and gradient HPLC methods.

Common Synonyms

  • Aqua
  • Dihydrogen monoxide
  • Dihydrogen oxide
  • Oxidane

Storage Conditions

Keep tightly closed and protect from particulate, ionic, organic and microbiological contamination that could affect chromatographic background. Use dedicated clean dispensing practices appropriate to HPLC mobile-phase preparation.
