Solvenţi pentru cromatografia de lichide, LiChrosolv®

 

With their low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. They are produced from specially selected raw materials, and undergo a number of purification steps prior to final packaging. 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 you to minimize the gradient effect of the solvent involved – for example in enantiomeric separations on chiral phases. In addition to LiChrosolv gradient and isocratic grade Merck Millipore presents a new generation of LC-MS LiChrosolv® hypergrades which have been accurately tested for LC-MS suitability, and meet all the requirements of modern LC-MS ionization methods (ESI/ APCI – positive and negative mode). Thanks to their low level of ionic background and low ion suppression, they ensure high reproducibility and high ionization efficiency.
