NUCLEODUR® C18 Pyramid
high purity silica phase for HPLC
octadecyl modification with polar endcapping suitable for aqueous eluents · endcapped · 14 % C · USP L1
Properties

	key features: stable in 100 % aqueous mobile phase systems interesting polar selectivity features excellent base deactivation; suitable for LC/MS due to low bleeding characteristics
	technical characteristics: special phase with polar endcapping pore size 110 Å; particle sizes 1.8 μm, 3 μm and 5 μm 7 and 10 μm particles for preparative purposes on request carbon content 14 %; pH stability 1 – 9
	recommended application: analgesics, penicillin antibiotics, nucleic acid bases, water-soluble vitamins, complexing agents, organic acids
