Thermoresponsive poly(N-vinylcaprolactam) as stationary phase for aqueous and green liquid chromatography [PDF]

, 2010
Poly(N-vinylcaprolactam) (PVCL) connected to aminopropyl silica is a new stationary phase for temperature responsive liquid chromatography (TR-LC). PVCL shows a transition from hydrophilic to hydrophobic interaction between 30 and 40 degrees C.
