For example, there are columns that can stand high temperatures, which are used to fractionate polymers that are soluble only at high temperatures, such as polyethylene or polypropylene.
There are also columns suitable to work with aqueous solvents, those columns are packed with a material known as ultrahydrogel, which is basically a crosslinked hydroxylated polymethacrylate; these columns are used
with polymers that are soluble in water, such as poly (acrylic acid), poly(vinyl alcohol), poly(ethylene glycol), etc.
