To address the growing needs of HPLC solvents suitable for gradient analysis in pharmaceutical, biotechnology, cosmetic and chemicals industry, Finar has developed HPLC solvents to address the specific needs of these industries. Finar Acetonitrile and Methanol HPLC Gradient solvents are purified with advance purification technology which remove impurities interfering in Gradient HPLC analysis. These products are tested as per American Chemical Society, 10th edition on gradient test and also tested on lower wavelength for gradient application. Label provides actual UV graph batch analysis from 195nm to 230nm. These ranges of solvents are free from UV absorbing impurities and ensure consistent result in gradient analysis.
