NUCLEOSIL C4

by MACHEREY-NAGEL

NUCLEOSIL® standard silica phases for HPLC

Features

NUCLEOSIL® is a family of totally porous spherical silicas with a very pure and uniform SiO2 structure

Wide acceptance as routine packings for very different fields of chromatography
One of the first spherical silicas used in HPLC
Developed in the early seventies, it became a world-renowned HPLC packing
Still found in many analytical and preparative applications
An absolutely reliable choice in HPLC
The largest variety of modified HPLC silicas available on the market

NUCLEOSIL® C4 - Butyl modified silica phases for HPLC
Medium density modification, endcapping · ~ 2 % C · USP L26

Features

Endcapped phases for RP and ion-pairing chromatography
Available pore sizes 120, 300, 500, 1000 and 4000 Å, available particle sizes 5 µm, 7 µm and 10 µm
Separation mechanism based on hydrophobic (van der Waals) interactions, some residual silanol interactions
Retention times are shorter than on C8 and C18 phases
pH stability at 20 °C: 2–8

Application areas:

Hydrophobic compounds Peptides Proteins
