MQuant® titrimetric and colorimetric methods.

Supplier: Merck

SupraSolv® ECD and FID is specially developed for gas chromatography in combination with ECD (Electron Capture Detetor) and FID (Flame Ionisation Detector). SupraSolv® solvents offer the largest specified retention time range, a clear baseline and a minimal signal-to-noise ratio leading to reliable and reproducible analysis results.

Supplier: Merck

LiChrosolv® hypergrade is accurately tested for LC-MS suitability, and meets all the requirements of modern LC-MS ionisation methods (ESI / APCI - positive and negative mode).

Supplier: Merck

HPTLC plates, unmodified silica gel 60
This range of plates uses an optimised Merck silica gel 60 with a particle size of only 5 to 6 µm, which results in higher packing density and a smoother surface, therefore, reducing band diffusion. Less sample is required, 0,1 to 0,5 µl than for classic TLC.

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.

RP-2, RP-8 and RP-18 are based on silica gel 60 modified with aliphatic hydrocarbons. The chain length, in combination with the degree of modification, defines the ability to tolerate water in the solvent system and strongly affects retention. Migration time increases in the order RP-2, RP-8 and RP-18 using the same solvent composition. RP-8 and RP-18 can be run with up to 60% water in the solvent system.

Xylenol orange tetrasodium salt, AnalaR NORMAPUR® ACS, Reag. Ph. Eur. indicator for metal titration

Supplier: Merck

TLC plates, unmodified silica gel 60
Merck silica gel 60 has a unique polymeric binder that results in a uniform, hard surface that will not easily crack or blister. This smooth, extremely dense plate coating ensures narrow bands and maximum separation efficiency with the lowest background noise. Layer thickness 250 μm and particle size of 10 to 12 µm. Two inorganic fluorescent indicators for UV detection of colourless substances.
