- Chemists and lab technicians use this Lab Alley brand organic solvent as a mobile phase in HPLC because it minimizes interference with chromatographic results.
Â
High performance liquid chromatography (HPLC) is a technique used in analytical chemistry to separate the components of a mixture and identify and quantify each component. Ethanol is a green organic solvent used for green liquid chromatography.
Ethanol is a polar solvent used as a mobile phase in reversed-phase HPLC. Because ethanol is miscible with water and other organic solvents such as acetonitrile and methanol, it is an excellent solvent for HPLC analysis. Lab Alley brand HPLC grade ethanol 190 proof is used commercially and industrially as a reagent in synthetic organic chemistry, in the pharmaceutical industry, in research and academia. It is used as a solvent for herbal and plant-based extraction processes.
