Acetonitrile : Water 20:80 ratio HPLC Grade | CAS: 75-05-8 | M.F: CH3CN | MW: 41.05, Buy now for reliable and Reproducible results from LiChrom HPLC Solvents at Chemical World.

Acetonitrile used in HPLC is a highly polar organic solvent. When combined with water, the concentration of acetonitrile decreases. This reduction in concentration enhances chromatographic performance, particularly for early eluting, hydrophilic peptides. Additionally, it undergoes ultra-filtration to minimize particulate contamination.

LiChrom is a high-quality line of products tailored to meet the needs of Liquid Chromatography. Suitable for all varieties of Liquid Chromatography processes, LiChrom products hold the highest quality and performance standards. In case of any HPLC analysis, LiChrom offers complete coverage with its high-purity solvents, buffer salts, and ion pair reagents. Together ensure dependable and reproducible results in every single analysis.

Application :

Acetonitrile: Water 20:80 ratio HPLC is used as a solvent in HPLC to retain or elute chemical species of interest from a stationary phase.
It may also be used as a needle or injection port wash solution.
It is commonly used as a mobile phase in reverse phase chromatography.

Benefits :

Low chemical reactivity
High miscibility with water mixtures
Low viscosity
Low ultraviolet cut-off
Low metal ion content to ensure minimal metal contamination
