Polymer-Based Columns - RSpak
| RP18-415 |
· For reversed phase analysis of proteins and peptides
- large pore size |
| DS-613,413 |
· For reversed phase analysis of highly hydrophilic substances, which cannot be retained well by ODS columns. |
| RP18-613,413 |
· High-performance (high-theoretical-plate-number) version of DS-613 and DS-413 |
| DE Series |
· Widest application because of similar polarity compared with ODS columns
· Wide pH range enabling use in 100% water |
| DM-614 |
· For the analysis of amino acids and water-soluble vitamins |
| NN-814,614,414 |
· The packing material contains a trace amount of sulfo groups, it supports multi mode (reversed phase and cation exchange) analysis
· Ideal for complex samples cantaining neutral and ionic substances |
| JJ-50 |
· The packing material contains a trace amount of quanternary ammonium groups, it supports multi mode (reversed phase and anion exchange) analysis
· Ideal for complex samples cantaining neutral and ionic substances |
| DC-613 |
· For the normal phase analysis of saccharides |

Polymer-Based Columns - ODP2 HP
| ODP2 HP |
· Improved theoretical plate number compared with general polymer-based columns, almost twice as good
· Retain both polar and non-polar small molecules
· No protein retention
- can analyze small molecules in the presence of proteins
· Ideal for LC/MS analysis
- retain sharp peak shape even in low salt concentration |

Characteristics and Application of Normal and Reversed Phase Columns
RSpak RP18-415 has a pore size of approximately 450 angstrom and are suitable for the analysis of proteins. The Asahipak ODP, C8P and C4P have a pore size of approximately 250 angstrom and are suitable for peptides.
The RSpak DE-613 and DE-413 have a pore size of approximately 100 angstrom can be used for the analysis of a low molecular weight substances such as oligopeptides. Should none the DE-613, 413 or ODS columns give satisfactory results due the non-retention of the sample then the use of the RSpak RP18-413 or the RP18-613 which have a lower polarity can be recommended.
