Shodex (Resonac) / RSpak

RSpak

The RSpak columns from Shodex are based on polymers. In this product line there are columns for the reversed phase as well as for the ion exclusion mechanism. The reversed phases do not have a C18 group, so that the columns are very stable and have a long life time.

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

general application, similar polarity to ODS columns
can be used in 100% water
for analysing vitamins, preservatives and organic acids

RSpak DM-614

for analysing amino acids and water-soluble vitamins

RSpak DS-413 and DS-613

for the reversed-phase analysis of highly polar substances that are not retarded on an ODS column

RSpak KC-811

for the analysis of organic acids
separates compounds with ion exclusion and reversed phase mechanism
