Application

Expiration Dated
HPLC
Water is used
  • As a solvent for preparing buffers during the cell lysis process.
  • As a component of the mobile phase in HPLC–UV–diode-array detection for the separation and detection of analytes.
  • In the determination of catechins and xanthines in tea beverages by micellar electrokinetic chromatography.

General description

Water is used as a solvent for isocratic elution in both cation and anion chromatography. It is also essential for preparing standard stock solutions. Additionally, water is used to evaporate samples under a nitrogen stream in a water bath, allowing for concentration prior to LC-MS-MS analysis.
