n-Esano, LiChrosolv® for liquid chromatography, Supelco®

Fornitore: Merck

Descrizione: 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 minimises the gradient effect of the solvent involved.

Dimetilsolfossido, Uvasol® per spettroscopia, Supelco®

Fornitore: Merck

Descrizione: Accurate analytic results in UV/Vis and infrared spectroscopy depend on the use of very pure solvents for sample preparation. The Uvasol® solvents range has been specially designed for spectroscopy and other applications requiring solvents of the highest spectral purity. The refinement process allows a greater degree of security in applications and avoids misinterpretation of analytical results caused by traces of UV, IR and fluorescence contamination. Uvasol® solvents offer best UV transmittance. In all specifications the minimum transmittance for five typical wavelengths are identified. Furthermore the transmittance is specified in accordance with Reag. Ph. Eur. and ACS.
