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)
