USP Column Recommendation
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 Number | USP Description | PSS Column |
---|---|---|
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 (30/100 Å), NOVEMA MAX |
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 (100 Å) |
L37 | Polymethacrylate gel packing having the capacity to separate proteins by molecular size over a range of 2 000 – 40 000 Da MW. | SUPREMA (30 Å) |
L38 | Methacrylate-based size exclusion packing for water-solubles. | SUPREMA |
L39 | Hydrophilic polyhydroxymethacrylate gel of totally porous spherical resin | SUPREMA |
L58 | Strong cation-exchange resin consisting of sulfonated cross-linked styrene-divinylbenzene copolymer in the sodium form, about 6 to 30µm diameter. | MCX |
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 (300 Å) |
