Preparative chromatography system from Jasco
Jasco has developed a Preparative SFE/SFC (supercritical fluid extraction/ supercritical fluid chromatography) system featuring a versatile modular design.
The system incorporates JASCO'S patented back-pressure regulator which allows control of system pressure regardless of solvent composition and flowrate. The pumping system is based on the performance of the company's 1500 series analytical SFE/SFC system and can deliver up to 120ml/min of CO2 and 60 ml/min of modifier and flush solvents at pressures up to 35 MPa (5000 psi). Injections can be manual or fully automated, and repetitive injections can be performed to overlay chromatographic runs. Detection choices include UV and/or CD with MS interface capability.
Jasco says that fraction collection of up to 8 fractions by time, signal level and/or slope is standard and spectral purity monitoring of Chiral molecules using the g-factor output of the CD detector is standard with the CD detector option.
Up to 20 mm x 250 mm columns can be accommodated in the column oven while 30mm and larger columns can be used outside the oven.
