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.

L20 |
Dihydroxypropane groups chemically bonded to porous silica particles, 3 to 10µm in diameter. |
|
|
L21 |
A rigid, spherical styrene-divinylbenzene copolymer, 5 to 10 µm in diameter. |
|
|
L22 |
A cation group resin made of porous polystyrene gel with sulfonic acid groups, about 10 µm in size. |
|
|
L23 |
An ion exchange resin made of porous polymethacrylate or polyacrylate gel with quaternary ammonium groups, about 10 µm in size. |
|
|
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. |
|
|
L39 |
Hydrophilic polyhydroxymethacrylate gel of totally porous spherical resin |
|
|
L58 |
Strong cation-exchange resin consisting of sulfonated cross-linked styrene-divinylbenzene copolymer in the sodium form, about 6 to 30µm diameter. |
|
|
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) |
