Product: SFC Chiral Analysis
View more products below
The
Jasco SFC Chiral Analysis System is a fully integrated SFC system with a circular
dichroism (CD) detector that is optimized for high-sensitivity analysis of chiral
compounds. The system delivers supercritical fluids at low flow rates, which results
in superior resolution in a wide range of applications. The elimination of organic
solvents reduces cost and environmental exposure and the use of supercritical
fluids enables faster and cleaner sample recovery.
The SFC Chiral Analysis System is comprised of integrated components of Jasco’s
modular LC-2000 HPLC system with the addition of an SFC/SFE CO2 pump
and patented back-pressure regulator. The system features Jasco’s circular dichroism
detector, which provides unmatched sensitivity and stability for chiral analysis.
The CD detector can simultaneously determine both CD and UV absorption of the
sample in the same cell for the direct determination of optical purity.
