TRITON™ X-100 (Polyethylene glycol tert-octylphenyl ether)

Supplier: Merck

Our NH₂, CN- and DIOL-modified silica sorbents are less polar then conventional silica phases, making them ideal for separating hydrophilic or charged substances. Our moderately polar cyano- and diol-modified silica plates can be used for both normal phase and reversed phase systems. An alternative to PEI cellulose, amino-modified NH₂ plates provide weak basic ion exchange characteristics with special selectivity for charged compounds.

NUCLEOSIL® C18 columns with octadecyl modified silica phase for HPLC.

Supplier: Merck

apHera™ reversed columns were developed specifically to provide the superior advantages of both silica and polystyrene columns, without the disadvantages of either. This was accomplished using a vinyl alcohol copolymer base that keeps the surface wetted even with high carbon loads. The porous structure has an average pore diameter large enough to produce ideal results for small analytes, peptides and small proteins.

This non-polar column is specially designed for reproducible analyses of plant sterols, cholesterol, and other animal sterols.

Supplier: Merck

These non-polar methyl silicone bonded poly(dimethyl siloxane) columns are used to separate the sample components according to boiling point.

Supplier: Merck

Solid phase extraction disks provides faster flow rates and exhibits less clogging than PTFE discs for the extraction of organic contaminants from drinking water samples.

Supplier: Merck

This intermediate polarity column is mainly designed for analyses of volatile organic compounds (VOCs), offers great retention and resolution of highly volatile compounds.

Supplier: Merck

These columns are situated between the traditional non bonded cyanosilicone phases SP-2330 and SP-2340 in polarity. The high polarity of this phase allows the separation of geometric (cis/trans) fatty acid methyl ester isomers as a group.
