HPLC columns for better sensitivity and stability
Supelco, a division of Sigma-Aldrich, has introduced the new Ascentis C8 HPLC column, which it says offers superior retention power and resolution even for difficult to separate analytes
The company says its scientists have combined proprietary advances in bonding chemistry, a 'revolutionary' approach to endcapping, and ultra high purity silica to create what it calls surface-optimised technology.
Featuring C18 and RP-amide phases, the Ascentis column family is engineered with high surface coverage to provide maximum HPLC performance.
Ascentis HPLC columns offer near-perfect peak symmetry; excellent retention, even for many difficult to retain compounds; orthogonal selectivity between C18 and RP-Amide; ultra low MS detectable bleed; and the new RP-amide is compatible with 100% aqueous mobile phases, it says.
"We designed the Ascentis HPLC phases to provide retention and selectivity choices for HPLC method developers and chromatographers in all industries," said William Campbell, R and D manager at Supelco in Bellefonte, PA.
"Our research into bonding chemistry has led to the development of our optimised-surface technology, ensuring the Ascentis phases deliver stable and reliable analyses and purifications".
