Quality Control Lab Reagents
Methanol (HPLC)
Methanol, also known as HPLC methyl alcohol, is a polar protic solvent that is commonly used in high-performance liquid chromatography (HPLC) as a mobile phase component. It’s often used in reverse-phase HPLC to separate polar compounds and in normal-phase HPLC to separate non-polar compounds. It is used in HPLC for the following reasons: low boiling point, high solubility, low toxicity, and high purity. It is also suitable for different types of detectors and can be used in the wavelength between 230-190 nm (Far UV region).

Acetonitrile (HPLC)
Acetonitrile HPLC grade is a solvent with a purity of at least 99.93% and a CAS number of 75-05-8. It’s also known by the synonyms ACN, ethyl nitrile, cyanomethane, and methyl cyanide. Acetonitrile is a popular solvent for chromatographic separations because it has low viscosity, low chemical reactivity, and high miscibility with water.
