HPLC SAMPLE PEAK RECYCLER™

 

The 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 most  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.

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 and two available time programmable contact closure are all that are needed to operate.

  • This product uses a technique developed by us in 1996 known as "Column Leap Frogging" which places one column in front of the other making the column appear to be many times the length of the original.
  • Simply recycle the sample as many times as needed until the desired resolution is obtained..
  • Great for difficult to resolve chiral racemates that are partially resolved.
  • Does not run the sample back through the pump head, which can dilute the sample, but rather passes it onto one of two identical columns in a "leap frog" manner.
  • The detector can be placed after each successive column outlet to monitor the progress of the separation, without disturbing the run. This allows real time monitoring of the sample not available with any other system on the market.
NOTE: In the literature we have seen several chromatographers who have erroneously reported and published about a "unique" HPLC technique known as "Simulated Moving Column" or SMC chromatography. Please keep in mind that while some of them have reported that they designed/developed 'SMC' that it is NOT a new or unique technique at all as we developed the first commercial multi-column analytical recycler known as the LC Sample Peak Recycler™ and have correctly coined the term "column leap frogging" not SMC to describe this technique. We introduced this leap frogging technique and product in 1996 and have sold the product, the LC Sample Peak Recycler™, Model CS3080, since that time (many of you have seen it at the Pittcon and HPLC ## shows or use it in your lab). Please remember to always check your information and references first as well as perform a basic search on the Internet (it is so easy today) BEFORE you claim to have developed a technique already in use and having been commercially available to the public for over a decade before your publish an article or application note.
