I am looking to purchase a analytical system. There are HPLC available around, but old. I am trying to figure out if ionic chromatography could cover most of my needs. I work on plant secretions and my samples are mostly aqueous nutrient solutions (I.e water containing inorganic anions and organic molecules from the plant)
Yes, you can use it easily. I have used it to analyze peptides containing 20 amino acids. But I do not know the effect of 10mM inorganic anions on the analytical column.
You need a good HPLC system in addition to IC. You may get by with an ion chromatograph for AA but not for large peptides.
Arnab Chowdhury Andrei Blasko Thank you for your answers. Most of the peptides I need to analyze are small: glutathione and dipeptides. I think that I would really need to load my sample in a machine to see what comes out.
