NUCLEODUR CN/CN-RP

NUCLEODUR® CN / CN-RP
high purity silica phase for HPLC
cyano (nitrile) modification for NP and RP separations 7 % C · USP L10
Features

	key features: high retention capacity especially for very polar and unsaturated compounds multi-mode column (RP and NP) widens scope of selectivity stable against hydrolysis at low pH (working range pH 1 – 8)
	technical characteristics: cyanopropyl modified high purity silica; pore size 110 Å, particle sizes 3 µm and 5 µm; 7 % C; special endcapping high reproducibility from lot to lot; different retention characteristics in comparison to C8 and C18
	recommended application: tricyclic antidepressants, steroids, organic acids
