Supplier: Merck
Description: Chromolith®, Chromolith® column coupler

SDS

Supplier: Merck
Description: Made of highly porous monolithic rods of silica with a revolutionary bimodal pore structure, therefore, high separation efficiencies are reached under low back pressures. These columns have long lifetimes within pH range of 2,5 to 7,5, high matrix tolerance and speed of analysis. Technical information.

SDS

Supplier: Merck
Description: Monolithic silica technology: A new age in chromatography. Chromolith® columns are based on silica so existing methods can be easily transferred with only minimal investment in new method development work. 'Sol-Gel' technology allows highly porous monolithic rods of silica to be formed. These feature a bimodal pore structure provides a unique combination of macropores and mesopores.

SDS

Supplier: Merck
Description: Chromolith® DIOL columns are useful as an intermediate polarity media between C18 and silica. Diol functionalised media is less polar and can have different selectivity. Chromolith® DIOL can be used with a wide range of solvents in both normal and reverse phases. In normal phase mode, the diol phase provides an alternative selectivity compared to silica whilst additionally demonstrating longer retention times that help to obtain separation. In reverse phase mode, compounds such as water-soluble vitamins, sugars or amino acids are easily baseline separated using simple mobile phases. Chromolith® DIOL columns have long lifetimes within pH range of 2,5 to 7,5, high matrix tolerance and speed of analysis.

Supplier: Merck
Description: Cyano columns are generally more polar than traditional alkyl silica columns. The functional groups are highly ordered, reducing steric hindrance for the solute. The modification also allows cation exchange activity, which is higher at neutral pH than in acidic conditions. Chromolith® CN columns are suitable for the separation of alkaloids, oils, flavonoids, glycols, phenols, phthalates, steroids and sulfonamides.

SDS

Supplier: Merck
Description: Pore volume: 2,9 ml/g.

Supplier: Merck
Description: These columns have been designed following the high demand for suitable analytical methods for process monitoring and quality control of wide pore biomolecules. Accurate analysis of proteins, antibodies and large peptides requires columns with good permeability, along with better mass transfer and selectivity. In order for size exclusion not to influence the separation, the pore size should be approximately ten times larger than the molecule being analysed.

Supplier: Merck
Description: Fast nano-LC for proteins and peptides. Chromolith® CapRod® capillaries combine the speed of monolithic silica technology with the sensitivity of nano-LC, thus enabling high speed high sensitivity LC-MS analytics.

SDS

Supplier: Merck
Description: Chromolith® Prep monolithic stationary phases are new ultrapure silica phases which gain their special properties from a bimodal pore structure. This structure is a property of the new 'Sol-Gel' technology and consists of macropores and mesopores. The mesopores with an average diameter of 12 nm, form the fine porous structure of the column interior and create a very large surface area on which adsorption of the target compounds occurs.

SDS

Supplier: Merck
Description: Specially developed screw caps for direct instrument connection of Merck S 40 threaded bottles ensure safe handling of solvents in the lab and protect human health, the environment, as well as solvent quality.

SDS

Supplier: Merck
Description: Ideal for preparing buffer solution according to WEISE for staining of blood smears.
