Craft Technologies Uses Selerity Technologies' Polaratherm
News Aug 09, 2005
Craft Technologies has announced that it has been experimenting with sub-ambient temperature separations, in particular, using the Polaratherm from Selerity Technologies (Salt Lake City, Utah).
The separation of phytochemicals in natural products, including anti-oxidants (carotenoids), has seen renewed interest for their use in nutraceuticals. It is believed that the anti-oxidant capabilities of carotenoids may reduce the risk of developing cancer.
Using Selerity's Polaratherm, Craft Technologies has conducted experiments to separate retinol and retinyl esters, carotenoids, and tocopherols. The results have all demonstrated that sub-ambient and programmable temperature separations using the Polaratherm chromatographic separations.
According to Selerity, its Polaratherm is a HPLC column compartment capable of controlling the temperature from sub zero to 200ºC benefiting from two modes of operation, temperature programming and isothermal.
HPLC column compartment is designed to allow and regulate high, ambient, low or dynamic temperatures for selectivity tuning and improved HPLC separations and the equipment is applicable to most vendor HPLC systems.
Stereochemistry is a science of reflection. Two chemical molecules with the same composition and structure, but with one as the mirror image of the other, can produce wildly varying effects. But University of Utah chemist Matt Sigman has been developing a way to get a better grasp on this tricky field of chemistry.READ MORE
