Centrifugal Planar Chromatography (CPC) Has New Capabilities

Traditional CPC (also known as Rotation Planar Chromatography (RPC)) consists of a rotating glass plate coated with silica gel of different thicknesses for only normal phase chromatography. Samples inserted in the center pass through the media and eluent works its way to the perimeter and is collected for detection. CPC has been around for decades and, while it provides for quick, convenient analysis of samples, has the drawback of not being capable of reverse phase separation and the inconvenience of coating glass plates.

The new CPC device dramatically distinguishes itself and offers the following:

·         It combines the advantages of both Preparative Thin Layer Chromatography (PTLC), Column Chromatography (CC) and preparative High Performance Liquid Chromatography (p-HPLC)

·         As compared to flash cartridge systems it has an additional, unique parameter (advantage) of centrifugal dynamics (ie. rapid and efficient separation of compounds (with close Rf values) in a mixture.)

·         Rotational dynamics has an effect on an individual component when in a mixture with different molecular weights. This is a beneficial factor for the separation and purification process.

·         Quick and efficient separation of diastereoisomeric mixtures

·        Patent-pending Rotary Disc allows for any bulk adsorbent (normal to reverse phase) and media (ion exchange, gel filtration, size exclusion) for every type of purification (natural products, reaction mixture, proteins, etc.)

·         Updated with modern technology: Instrument, Software, Gradient Pump, Detector & Fraction Collector

Question Title

* 4. Are you familiar with Centrifugal Planar Chromatography?

Yes, I presently use CPC - If yes, please proceed to Question #7

Yes, but I know longer or have never used it - If yes, please proceed to Question #6

No - Please go to next question

Question Title

* 5. New CPC captures media in a rotating "cassette" that can come prefilled or be packed by the operator, allows reverse phase (not previously possible) and minimizes band broadening. Would these features be of use to you?

No, my present method(s) meets my needs.

Yes, I would consider it depending on initial cost.

Yes, I would consider it, but have plenty of capacity now.

Question Title

* 6. If you have not used why not, or if you no longer use CPC why?

Was limited in capability - switched to flash cartridge.

Preparing (coating) glass plates was inconvenient

Obtaining pre-coated plates was slow or expensive.

Equipment was unreliable - service difficult

CPC equipment was sold

CPC equipment was scrapped.

CPC equipment is in storage

Question Title

* 7. If you still use CPC

I have no need of the new features cited

I would be interested in a device with the new features

I have other devices (e.g. flash cartridges) that meet my needs and therefore am not interested in the new features offered with improved CPC

I use CPC rarely

I use CPC often
