Process Scale Chromatography
For successful Process Liquid Chromatography the question below have to be answered:
a. What are your sample compounds?
Organic Synthetic Compounds with MW <2000 (Heterocycles, Vitamins, Organo-metallics, Hormones, Pesticides)
Natural Products with MW <2000 (Saccharides, Lipides, Phospholipides, Isoprenoids, Steroids, Alkaloids, Flavenoids, Terpenes, Polyphenols, Saponins, Proanthocyanidins, Tannins etc from a wide range of matrixes)
Amino Acids, Peptides, Oligonucleotides
Large scale racemate purification
Inorganics Separation (Cations and Anions, Metals, Nobel Metals, Acids, Alkalis, Industrial Waste, Hydrometallurgical- refining, leachages, extracts, precipitants)
Protein, Biomarkers and Biotherapeutic Proteins (Enzymes, Membrane Proteins, Recombinant Proteins, Antibodies, extracts from mammalian Tissue, Erythrocytes, Yeast, Bacteria)
b. Sample preparation?
In what condition is the compound supplied for chromatography processing?
Is sample preparation necessary?
What type of sample preparation is necessary?
c. Environmental factors
Does the compound have to be process in organic solvent or can it be done in aqueous systems?
Is ATEX configuration necessary?
Are there facilities for solvent recycling?
What shall happen with the by-products?
d. Process equipment selection
Anticipated Business volume (g, kg or tons per day/week or month of pure compound)?
Level of purity to be achieved?
Envisaged process life?
Envisaged process and maintenance costs?
Envisaged capital cost?
Strategy to finance capital investment?
Separation materials to be used?
Has a phase evaluation been conducted to assure selection of the most effective material.
e. Preferred Process Mode
Single columns batch chromatography (Flash, MPLC, HPLC, Expanded Bed Purification, new experimental processes)?
Parallel column chromatography?
Continuous column processes (SMB , SSR)?
New experimental processes?
