M-Clarity™ quality level = MQ100
Offering a high degree of UV transmittance, 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, Merck Millipore offer solvents in ’gradient grade’ as well as ’isocratic grade’. This enables you to minimise the gradient effect of the solvent involved.
The LC-MS LiChrosolv® hypergrade quality solvents are accurately tested for LC-MS suitability, and meet all the requirements of modern LC-MS ionisation methods (ESI/ APCI – positive and negative mode) with low level of ionic background and low ion suppression, they ensure high reproducibility and high ionisation efficiency.
