Description

Acetonitrile : Water 20:80 ratio HPLC | CAS: 75-05-8 | M.F: CH3CN | MW: 41.05, Buy now for reliable and accurate results from LiChrom HPLC Solvents. All LiChrom Products are exclusively distributed by Dawn Scientific Inc.

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 products are designed specifically for Liquid Chromatography. LiChrom products exceed the rigorous requirement of HPLC analysis in various industries. Apart from HPLC- solvents, the LiChrom series encompasses HPLC-grade buffer salts, and HPLC ion pair reagents. These products provide the highest levels of accuracy and precision, as well as reproducibility of results. LiChrom, only through Dawn Scientific Inc., ensuring that your chromatography requirements will be met.

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
