Supelco(R) Expands Ascentis(R) Express HPLC Columns Line for High-Speed and High-Efficiency Separations
ST. LOUIS, Sept. 3 /PRNewswire-FirstCall/ -- Supelco, a division of
Sigma-Aldrich (Nasdaq: SIAL), has expanded the Ascentis Express product
line (http://www.sigma-aldrich.com/express), a family of innovative HPLC
columns designed to provide the analysis speed and resolving power of
sub-2-micron columns with a 50% reduction in backpressure. Ascentis
Express RP-Amide, an embedded polar group chemistry, provides an alternate
selectivity to the conventional C18 and C8 phases.
"The combination of the RP-Amide advanced bonding chemistry and the
Fused-Core(TM) particle provides a polar column for high-speed and
high-resolution separations," said Wayne K. Way, Marketing Manager at
Supelco inBellefonte, PA. "The Ascentis Express RP-Amide provides
improved peak shape for basic compounds."
The key technology in the Ascentis Express column is the Fused-Core
particle. These high-purity silica particles measure 2.7 microns overall,
with a 0.5 micron-thick porous shell. Relative to columns using
conventional sub-2-micron particles, Ascentis Express columns generate
comparable efficiencies but with half the backpressure.
Supelco's offering of HPLC products is one part of Sigma-Aldrich's
technological and value-driven products that, combined with our services
and support, provide complete analytical applications solutions.
