Méthanol, Uvasol® for spectroscopy, Supelco®

Supplier: MilliporeSigma

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 5 typical wavelengths are identified. Furthermore the transmittance is specified in accordance with Reag. Ph Eur and ACS.

Méthanol, anhydrous (max. 0.003% H₂O), Seccosolv® analytical reagent, Supelco®

Supplier: MilliporeSigma

These reagents are produced using specially selected distillation methods that ensure consistently high dryness and batch-to-batch consistency. To protect the quality of these products even better from potential contaminants, a septum seal cap provides multiple layers of protection to keep solvents in flawless condition before, during, and after removal.

Méthanol, LiChrosolv® for liquid chromatography, Supelco®

Supplier: MilliporeSigma

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.
