The CS3080, LC Sample Peak Recycler (TM) allows partially resolved peaks to be separated automatically by recycling the sample back through the HPLC column to improve the separation. This system uses a technique correctly known as "Column Leap Frogging", not "Simulated Moving Columns" (or 'SMC) which was a name incorrectly applied to our device.  
  
Recycle chromatography is commonly used in preparative chromatography, but is rarely used in analytical chromatography. Numerous problems of sample dilution caused by running the sample through the pump head resulted in poor performance for analytical chromatography applications. This latest design, has solved all of the earlier design problems and now enables any chromatographer to take advantage of this powerful technique for analytical applications.  
  
Each system consists of both a modular control box 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, a high pressure rated flow cell and two available time-programmable contact closure are all that are needed to operate.  
  
Very popular with chiral applications, but can be used in any application where increased exposure to additional stationary phase will increase the probability of separation.
