The United States Pharmacopeia (USP) is a standard source for many pharmaceutical methods and it specifies columns by packing materials rather than by manufacturer.
Find below a list of the recommended PSS columns suitable for methods listed with the USP.
|USP No||USP Description||Matching PSS Material|
|L20||Dihydroxypropane groups chemically bonded to porous silica particles, 3 to 10µm in diameter.||PROTEEMA|
|L21||A rigid, spherical styrene-divinylbenzene copolymer, 5 to 10 µm in diameter.||SDV|
|L22||A cation group resin made of porous polystyrene gel with sulfonic acid groups, about 10 µm in size.||MCX|
|L23||An ion exchange resin made of porous polymethacrylate or polyacrylate gel with quaternary ammonium groups, about 10 µm in size.||NOVEMA Max|
|L25||Packing having the capacity to separate compounds with a MW range from 100 to 5 000 Da (as determined by polyethylene oxide), applied to neutral, anionic and cationic water-soluble polymers.||SUPREMA|
|L33||Packing having the capacity to separate proteins by molecular size over a range of 4 000 to 400 000 Da. It is spherical, silica-based, and processed to provide pH stability.||PROTEEMA |
|L37||Polymethacrylate gel packing having the capacity to separate proteins by molecular size over a range of 2 000 – 40 000 Da MW.||SUPREMA|
|L38||Methacrylate-based size exclusion packing for water-solubles.||SUPREMA|
|L39||Hydrophilic polyhydroxymethacrylate gel of totally porous spherical resin||SUPREMA|
|L59||Packing having the capacity to separate proteins by molecular weight over the range of 5 to 7 000 kDa. It is spherical (5 - 10µm), silica-based, and processed to provide hydrophilic characteristics and pH stability.||PROTEEMA |
