Stability 100 C30-NE from Dr. Maisch HPLC GmbH is a high-purity silica-based HPLC column with a 100 Å pore size and a non-endcapped long-chain C30 bonded phase. The absence of endcapping leaves residual silanol groups accessible, which enhances secondary polar interactions and provides unique selectivity compared to standard endcapped phases.
With its very long alkyl chains, the column offers exceptionally strong hydrophobic retention and excellent shape selectivity for structural and geometric isomers, while its stable bonding chemistry ensures outstanding performance under extreme pH, high-temperature conditions, and aggressive mobile phases.
Stability 100 C30-NE columns from Dr. Maisch HPLC GmbH combine maximum hydrophobic retention, enhanced polar interactions, and superior robustness – the reliable choice for isomer and hydrophobic compound separations in HPLC.
