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 For applications click here.
