RSpak columns

RSpak DE, DM and DS series

Polymer-based RP columns for many different applications

Product information

The RSpak DE, DM and DS columns don't contain C18 as functional group, but they provide the reversed phase separation mechanism by the polymer particle itself. This makes them very stable, so the columns have a very long life time.

RSpak DE-213, DE-413 and DE-613

General purpose polymer-based column having similar polarity as ODS columns
Wide working pH range (from pH 2 to 12), usable in 100 % water and buffer solutions
extra small pore size of 25 Å
for the analyis of vitamins, preservatives, organic acids
Fulfill USP L71 requirements (polymethacrylate particles)

RSpak DM-614

Suitable for the analysis of amino acids and water-soluble vitamins
pH range from 2 to 10
Fulfills USP L39 requirements (polyhydroxymethacrylate particles)

RSpak DS-413 and DS-613

Suitable for reversed phase analysis of highly hydrophilic substances that are not well retained by ODS columns
Fulfill USP L21 requirements (styrene divinylbenzene copolymer particles)
