Gradient-grade solvents are suitable for liquid chromatography. These solvents are free from UV-absorbing impurities and ensure a consistent result in gradient analysis. Gradient grade solvents have undergone additional testing relative to isocratic solvents in order to ensure a low impurity gradient LC baseline and low gradient baseline drift.
