Developed by Chiralizer Services in 1996, the Model
CS3080, LC Sample Peak Recycler allows partially resolved peaks to be separated
automatically by recycling the sample back through the LC column to improve the separation
[PHOTO].
Recycle chromatography is commonly used in preparative chromatography, but is rarely used
in analytical chromatography. Numerous problems of sample dilution caused it to have poor
performance in analytical chromatography applications. This latest design, has solved all
of the earlier design problems of sending the sample back through the pump head and now
enables any chromatographer to take advantage of this powerful technique for analytical
HPLC.
Each system consists of both a modular electronic
controller and a remote high pressure, low delay volume (0.1 ul) valve. Designed to work
with most any manufacturers HPLC system, only a single HPLC pump, two identical columns
and two available time programmable contact closure are all that are needed to operate.
Also includes front panel column "leap frogging" switches.
