Reversed Phase (ODS) Develosil ODS-SR C18 Column
3 µm, 5 µm and 15/30 µm
Develosil ODS-SR shows the longest retention in our ODS phases, and suitable
for LC/MS because much organic solvent obtain high sensitivity.
Available Inner Diameters
- Semi-micro column: 1.0 mm, 1.5 mm, 2.0 mm
- Conventional column: 3.0 mm, 4.0 mm, 4.6 mm, 6.0 mm
- Preparative column: 8.0 mm, 10 mm, 20 mm, 28 mm
