Since work in gradient mode is commonly used in HPLC analysis, we offer Gradient HPLC quality solvents.
All these solvents are controlled in our analytical laboratories by the gradient assay, modifying the proportion of the solvent with water. Changing the polarity of the mobile phase leads to the retention of the possible impurities of the solvent on column head and then they are eluted when the polarity of the mobile phase is changed again. The chromatographic profile must not show any peak with height greater than the specified in the technical data sheet.
We offer improved specifications of HPLC gradient quality Acetonitrile, Methanol and Water so that they are adequate for use in UHPLC.
The HPLC range of products also includes the most usual ion pair reagents in HPLC.
