Understanding how Quattro CPC or Quattro CCC compliment your existing Preparative / Process HPLC, Flash Chromatography, SFC, or Synthetic Equilibium Reaction Synthesis, to make results unobtainable by a single techology, commercially possible

Chromatography can separate a single or specified mixtures of organic or inorganic compounds from complex mixtures. This is achieved by partitioning of your required compound(s) from complex mixtures, by optimising the target compound(s) differential affinity between a selected stationary and mobile phase, to yield the purity you require, for your research, or tonnes etc. per annum purification.

Solid – Liquid Chromatography (SLC) techniques, such as HPLC, SFC and Flash Chromatography, are the most common options, utilised, for analysis, and laboratory, pilot, or process scale preparations (variously picograms, to tonnes per annum).

But sometimes issues can occur with milligram to tonnes per annum, preparative or process chromatography, with “on column” absorption or degradation. Or target compound might be too dilute to recover at a sensible cost. Or the crude mixture contains compounds that poison the SLC column, so purification cost is unacceptable for commercial use.

Liquid – Liquid Chromatography (LLC) techniques, such as Centrifugal Partition Chromatography and Counter Current Chromatography, utilise the same ancillary pumps, injectors, detectors, fraction collectors, control and data systems as SLC. The CPC or CCC instrument will be designed to retain one solvent (stationary phase) from a biphasic solvent mix, whilst the other liquid phase, not being retained, becomes the eluent of the biphasic mixture (mobile phase), as it flows through, achieving the resolution you require.

This website, gives multiple examples, in easy to understand slideshows, of a very wide variety of research and commercial applications, of the benefits of appropriate choices for either only LLC or only SLC. If your application not shown, contact us on aecs@gmx.com for confidential discussions

But most importantly, we also show many examples where appropriate combining of LLC and SLC technologies, allows you to resolve problems, a single technology cannot solve, or a commercial purification, or equilibrium reaction that is not commercially viable, whilst sequential use of LLC and SLC, can provide answers to research applications, or commercial procedures.

Also shown on this Home Page are considerable details on the revised Quattro CPC & CCC, plus HPLC & Flash ranges. We are willing to personally lecture any of the slideshows shown, and / or personally discuss in confidence, your own research needs for Laboratory, Pilot and Process Chromatography, by CPC / CCC, or HPLC / Flash Chromatography, or appropriate combination.

We offer options for both Quattro CPC and Quattro CCC.

HOW…? A single Low-Cost IntroPrep CPC or CCC can cost similar to a single 50 x 250mm C18, Prep HPLC column, with 5um phase, yet prepare far higher mass of injected material, work in Normal Phase, Reverse Phase, Affinity Chromatography, Displacement Chromatography (pH Zone Refining), Ion Exchange Chromatography, Chiral Chromatography, Linear or Step Gradient or Isocratic Gradient Modes, Not be poisoned by a single Natural Product crude mixture injection, used for all ranges of Polarity etc. Plus work at sub 10 ml/min flow rates, so be utilised your standard 0.1 ml/min to 10 ml/min HPLC, and not need purchase of a more expensive 25 to 50+ ml/min Preparative HPLC ancillaries. Worth Thinking About…?

Centrifugal Partition Chromatographs offer the potential, through their modular construction, of triple layer, three dimensionally machined, 316 Medical Grade Stainless Steel (or Custom Material) Rotor Blocks, full control of dimensions of length, and diameter, plus number of CPC chambers. You may chose from a standard range of scale up stages, with AECS known properties, or request customised rotors to suit your specific requirements. We have to date very high success in predictable scaleup from laboratory Quattro CPC to process Quattro CPC, and also from laboratory Quattro CCC to pilot scale Quattro CCC.

In certain cases, clients have transferred Quattro CCC derived methods successfully to process Quattro CPC, though we do not recommend method transfer between LLC concepts, as it offers more risk of scale up failure, than if you stay with same LLC concept.


We believe high percentage Ionic Liquid Biphasics are the answer to major process CPC, because they are simple and easy to recycle the Biphasic Solvents, plus offer a huge variety of chemical selectivities to chose from. Ionic Liquids can be chosen to protect compound’s structure, or alternatively to cause a controlled reaction of compounds to effect, unique high yield synthesis of required products during the Quattro CPC run.

We can custom build both CCC & CPC units specific for your requirements because of our unique modular construction. Options of different CCC bore or CPC cell / chamber sizes, different volumes on the same instrument. We can custom design to accommodate your specific needs, within a mutually agreed budget. Other competitors cannot match our design and build flexibility. Just ask them and us to custom build to your specific needs and budget. We will custom build to match a mutually agreed requirement & price.

Successful Purification
Successful Purification

We list how Quattro Centrifugal Partition Chromatography & Quattro Counter Current Chromatography can offer unique research opportunities plus cost savings below.

AECS-QuikPrep Ltd has been conducting fundamental liquid-liquid chromatography research since 1993. We have innovated many important liquid-liquid chromatography instrument designs. Others have copied, but never bettered our designs, or vaguely approach the safety features of our instrumentation.

Laboratory Quattro CPC & Quattro CCC, offer you enormous scope for researching unknown bioactivities, purifying difficult to obtain pure compounds from complex mixtures, be they natural products or synthethetic products, and host of other opportunities, which are discussed in the above Applications and Method Training Page (see second Header Button).

Quattro CPC offers the potential for massive processing cost savings, as no need to buy any solid stationary phase. Additionally, there is the cost saving of not needing to pay for disposal of contaminated used solid, stationary (silica etc) phase. With elution – extrusion, each run has new stationary phase for maximum reproducibility. Also there is potential, independently proven, to achieve 95+% injection mass recovery, and 95+% purity. The injection mass per solvent usage can also result in considerable solvent cost savings. Also as with Flash Chromatography & Process HPLC, so with Centrifugal Partition Chromatography, and Counter Current Chromatography, with appropriate biphasic solvent choice, high cost efficiency is achieveable, through easy solvent recycling.

Contacting Us, Please Give Us Your Purification Needs, and Discuss If You Might Need a Feasibility Study

The fact that AECS QuikPrep Ltd’s experience in liquid-liquid chromatography instrument design, manufacture and research, dates from 1993, compares very favourably to many of our present competitor CCC and CPC companies. Sales to China, Singapore, Indonesia, Australia, Brasil, Chile, USA, Canada, Eire, Nothern Ireland, England, France, Germany, Spain, Finland, Chechia, Switzerland. Etc.

Irrespective if you are a Separation Scientist / Synthetic Chemistry / Natural Product Chemist / Petrochemical Chemist / Environmental Chemist, or need to purify / recycle precious metals, rare earths etc., we have products where we can assist you in the following.

To achieve saleable purified product, find previously unknown bioactive compounds, by isolating narrow polarity fractions, for bioassay testing, and / or prior to HPLC/GC-MS or NMR, purifying precious metals / rare earths, testing the content of competitors’ products, to forcing equilibrium synthetic reactions, from uneconomic yields, to economic yields. Or a wide variety of other tasks. These might be as varied as, the fractionation of wide polarity mixes, like engine oils / additives, or crude / refined oils, or huge conconcetration of trace compounds in freshwater, seawater or wastewater samples, or even automated, periodic checking, for trace compounds, in liquid process streams etc.

Your imagination is the only restriction to possible uses. Please view the Methodology & Applications Slideshows, or contact us to discuss your specific needs at aecs@gmx.com.

Option of 2, 3 or 4 bores/volumes on competitor’s CCC, you would need to purchase multiple instruments. Alternatively we could custom build according to your needs, all on one Quattro CCC. Worth Thinking about?

New Options for novel Quattro CPC™, Plus a Number of New Potential Uses / Advantages

The Sun Motion Rotors can be custom made in Stainless Steel or other materials, ie Titanium etc., for proteins etc.

Quattro CPC instruments can have different chamber designs, on different rotor block sets, plus can have 2 different id cell (chamber) bore configurations, in the same Quattro CPC instrument. This gives the potential for a method development rotor and process rotor in the same Quattro CPC instrument.

Quattro CPC is ideal for MABs, proteins, peptides & enzymes, other organic and inorganic purification by chromatography.

Quattro CPC can be used to extract target compounds from complex dissolved mixtures, when using either contaminated complex crude mixtures as the mobile or the stationary phase, depending on the CPC mode chosen.

AECS’ QuikPrep Ltds unique multi-block CPC rotor design offers multiple specification options and designs, which can allow us to design for maximum resolution, or maximum throughput, or a mutually agreed compromise.

The Quattro CPC conceptual design is massively less critical, if client induced mistakes cause CPC rotor blockage. A blockage in one rotor block, can be bypassed and a slightly reduced processing rate can continue. The user can at a convenient time, remove a matched pair, and dismantle, clean and reassemble the client blocked rotor, whilst keeping production going with 2 less rotor blocks, if this is required.

Such an occurance in a stacked disc CPC design means factory repair of the whole rotor assembly, and considerable total processing downtime.
