Do you have a substance that needs to be purified ?

Do you have a racemic mixture that you would like to separate into enantiomers ?

Do you have a peptide that needs to be cleaner than 98% ?

Then you have come to the right place !

prep4u purifies your substances and separates racemic mixtures into enantiomers

 

 

 

Chiral HPLC

The separation of image and mirror image – enantioseparation – is a special case.
Although the physical and chemical properties of enantiomers match to a large extent, they often have completely different biological activities.

 

Preparative HPLC

We have profound and longstanding experience in the area of preparative HPLC
regardless whether it is 100mg or 100kg that needs to be separated.
We have a careful look at your compound and decide individually which separation method is the most effective

 

Simulated Moving Bed (SMB)

SMB can be used for the separation of larger quantities (from 5-10kg).

This involves continuous chromatography whereby up to 90% less solvent can be used as this is recirculated.

 

Supercritical fluid chromatography (SFC)

State of the art is the so called Supercritical Fluid Chromatography (SFC), which uses CO2 as eluent.
This protects your sensitive substances and is extremely environmentally friendly (Green Chemistry).
We can perform small scale and lage scale separations.

Common detectors are available, such as UV, DAD, MS, RI, CAD and NMR.
