Tetrahydrofuran, LiChrosolv® for liquid chromatography, Supelco®
Supplier: Merck
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.

Metanol ≥99.9%, LiChrosolv® Reag. Ph. Eur., gradient grade for liquid chromatography, Supelco®
Supplier: Merck
Med sin höga UV transmittans, låga partikelinnehåll, aciditet, alkalinitet och inndunstningsrest är lösningsmedel i kvalitéen LiChrosolv® ideella för reproducerbara separationer. Då separationer vanligtvis utförs under gradienntförhållanden i analytisk HPLC erbjuder vi lösningsmidler i ”gradient kvalité” och ”isokratisk kvalité”. Detta för att minimera gradienteffekten av lösningsmedlet.

Kaliumbromid, Uvasol® för IR-spektrofotometri, Supelco®
Supplier: Merck
Potassium bromide is transparent from the near UV to long wave IR wavelengths. In IR-spectroscopy, solid samples which are difficult to melt or dissolve in any suitable IR-transmitting solvent, are analysed by grinding with potassium bromide powder, and pressing into a disc. This procedure has a high quality demand of the used potassium bromide. Potassium bromide Uvasol® is adjusted to a mean particle size of 150 μm. This is sufficient for the preparation of perfectly good pellets without the need for further pre-treatment and the associated risk of contamination. It also retains its powdery form over a period of years if stored in an airtight condition. Its physical suitability for pelletising is checked by a special application test and its chemical purity established by full spectrum FT-IR analysis.
