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.
IMPROVE RESOLUTION WITHOUT DEVELOPING A NEW
METHOD.
- Fantastic tool to resolve difficult chiral racemates
apart (*This is what it was developed for in 1996).
- Simply recycle the sample as many times as needed
until the desired resolution is obtained.
- Uses your existing HPLC Pump, two identical columns
and one HPLC Detector.
- 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. While we delight in
the fact that so many chromatographer's use our products and technology, we consider it
rude when we are not credited or referenced correctly by them. |
