Description
Column for reversed phase
Develosil ODS-UG
The 2nd generation of Develosil series, very standard column
This series is the column in which residual silanol by high-grade-ize and double end cap treatment of the silica gel which is a base
material was reduced compared with ODS. The peak tailing of a basic compound is suppressed and it has become very user-friendly

| Column name | Use |
| ODS-UG |
It is used when using an alkaline mobile phase. It ranks with ODS-HG and is a standard existence. |
| ODS-HG |
It is used when using an acid mobile phase. Although separation almost equivalent to ODS-UG is shown, ODS-HG of solid recognition ability is higher. |
| ODS-MG |
2 reaction type ODS. Compared with ODS-UG or HG, retention is a column for a separation improvement strongly. It can be used also for a mobile phase with much water composition. |
| ODS-SR |
The column which is proud of the retention greatest in a Develosil column The optimal column for earning retention. Loading dose increase of preparative isolation can be aimed at |
