Primesep D is a reverse-phase analytical column with embedded basic ion-pairing groups specifically design for direct plasma analysis.
- Does not retain high-molecular weight plasma components.
- Retains hydrophobic and acidic components.
- All mobile phases are LC-MS and preparative chromatography compatible (working pH range from 1.5 to 4).
Primesep D columns are available in all standard dimensions Column IDs: 22 mm, 10 mm, 4.6 mm, 3.2 mm, 2.1 mm, 1 mm, 0.5 mm, 0.25 mm Column Lengths: 250 mm, 150 mm, 100 mm, 50 mm, 25 mm, 10 mm Particles: 10 um, 5 um Pores: 100 A
