NUCLEOSHELL® Biphenyl
Core-shell technology silica phase for HPLC
Special biphenylpropyl modification with multi-endcapping · 5.2 % C
USP L11
Properties
Key features:
Based on core-shell particle technology for fast and efficient HPLC
Separation principle is determined by 2 retention mechanisms:
π-π interactions and hydrophobic interactions
Enhanced retention for aromatic and unsaturated substances
Excellent performance under highly aqueous conditions
Suitable for LC/MS due to low bleeding characteristics
Technical characteristics:
Biphenylpropyl modification; multi-endcapping; pore size 90 Å;
particle size 2.7 μm; carbon content 5.2 %; pH stability 1.5–8.5
Recommended application:
Overall sophisticated analytical separations, especially aromatic
and unsaturated compounds, mycotoxins, phthalates, pesticides, pharmaceuticals (e.g., antibiotics), hormones, and DNPH aldehydes
