The difference between acetonitrile and methanol used in reversed phase chromatography_Kain Industrial Additive

1, absorbance. acetonitrile hplc grade small. among the absorption spectra of commercially available hplc grades and premium grades of acetonitrile and methanol, acetonitrile hplc has the smallest absorption (especially at short wavelengths). the so-called hplc grade removes uv-absorbing impurities and limits the absorbance to within the specified value at a specified wavelength. during uv detection,…
