SiChem uses preparative HPLC columns with various stationary phases from polar to nonpolar and chiral

Preparative HPLC (NP/RP)


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



We can support your separation and purification. We can offfer you the following:

  • feasibility studies for (enantiomers) separation
  • HPLC method development and optimization of separation conditions
  • 100mg to 100kg: custom purifications / separations in (semi) preparative scale
  • Purification of peptides


How it works:

If you would like us to separate or purify one of your substances, simply send us a small sample (10 mg). Using this sample, we will analytically test the separating conditions and transfer these onto the preparative scale. It is even better if you already know the analytical conditions for your substance.
Please provide us with these conditions to enable us to see whether they are compatible with our preparative systems.
You will subsequently receive an offer from us with the exact costs. Should you decide not to accept
our offer, you will only incur the costs for method development  amounting to 950EUR !
