Chromatography

The LCPO has a strong expertise in chromatographic technics dedicated to polymers :
- Separation and structural identification (HPLC, GC-MS, LC-MS)
- Absolute and relative molar mass determination and polydispersity (SEC RI-UV-MALS)
- Polymers purification (Flash chromatography)
- Follow-up and development of organic syntheses (HPLC)
