Chromatographic acetonitrile refers to the acetonitrile reagent used for chromatographic analysis, chromatographic separation and chromatographic preparation.
The product has excellent batch stability and meets the indicators of the American Chemical Society ACS analytical solvent.
In high performance liquid chromatography (HPLC) analysis, the purity and quality of the mobile phase solvent have an important impact on the analysis results and the instrument itself.
Various trace impurities in the solvent will not only cause high baseline and ghost peaks, which will affect the qualitative and quantitative analysis results, but also may contaminate the separation column and block the system, causing instrument failure.
Knowing HPLC solvent specifications and related test methods can help HPLC users evaluate and screen HPLC solvents and reduce the negative impact of solvent impurities.
The unique properties of acetonitrile that distinguish it from other HPLC solvents (medium elution power, strong solvency, clear chromatographic peaks, low viscosity, low UV absorption relative to alcohols and esters) make it the most commonly used organic solvent. mobile phase components.
