| octadecyl group |
16 |
Mono-functional silylation on ultra-pure silica
gel makes this column suitable for the separation of a wide range
of compounds. |
| octadecyl group |
17 |
Multi-purpose, ultra-pure silica gel based
polymeric C18 column with
exceptionally strong acid resistance. |
| octadecyl group |
11 |
Reversed phase HPLC column, compatible with
100 % water based mobile phases! |
| pyrenyl ethyl group |
18 |
Multiple separation modes including
hydrophobic interaction, charge transfer and  -
interaction makes this column very unique. Especially useful for
structural isomer separation. |
| nitrophenyl ethyl group |
9 |
Similar to the PYE column with multiple
separation modes. Very useful for separations impossible with
standard alkyl chain columns. |
| pentabromo benzyl group |
8 |
Designed for the preparative separation of
fullerenes using carbon disulphide or toluene as mobile phase. |
| pyrenylpropyl group |
17 |
Economical preparative separation of
fullerenes (higher fullerenes, metal containing fullerenes) on an
analytical HPLC system. |
| diol group |
|
Silica-based gel filtration column for
high-speed separation of proteins and enzymes. |
| alkyl group |
|
Columns for organic GPC of polymers, choice of
60 A, 100 A, 300 A pore sizes. |
|
|
Normal phase chromatography without ionic
additives |
| alkyl or pheny group |
|
Wide pore reversed phase column with high acid
resistance recommended for the separation of proteins,
polypeptides, nucleic acids and other large molecules. |
| aminopropyl group |
4 |
Normally used for reversed phase
chromatography of various mono-, di- and oligosaccharides but can
also be used in normal phase adsorption chromatography with
non-polar organic solvents. |
| octabecyl group |
9 |
Generally recommended to improve retention of
very polar compounds. |
| octyl group |
10 |
Shorter retention than C18-MS-II
but otherwise provides excellent separation for many compounds. |
| butyl group |
7 |
Short alkyl chain length suitable for the
separation of more hydrophobic compounds. |
| trimethyl group |
5 |
Provides shorter separation time for classes
of compounds with wide range of polarities. |
| phenylethyl group |
10 |
Provides greater retention for aromatic
compounds. |
| cyanopropyl group |
7 |
Alternative to improve peak shape or shorter
retention times. |
| ion exchange groups |
|
COSMOGEL columns based on a hydrophilic
polymer gel; 4 types are available: DEAE and QA for anion
exchange-, and CM and SP for cation exchange chromatography. |
