Metanol atau disebut juga : MeOH, Hydroxymethane, Methyl alcohol, Carbinol memiliki tingkat transmisi UV yang tinggi dan jumlah partikel, keasaman, alkalinitas, serta jumlah residu evaporasi yang rendah. Sifat tersebut membuat LiChrosolv® menjadi larutan yang ideal untuk proses pemisahan menggunakan HPLC analitik. Selain itu, LiChrosolv® juga didesain dengan standar gradien dan standar isokratik, sehingga memungkinkan minimalisir efek gradient pelarut yang terlibat.
With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in "gradient grade" as well as "isocratic grade". This enables to minimize the gradient effect of the solvent involved.
