Adenosine is a ribonucleoside (adenine + ribose). ATP is a
particularly important nucleotide, serving as a universal
source of energy for biological processes.
The Ultra IBD column is particularly effective for retaining
and resolving complex mixtures of nucleotides, nucleosides,
and purine and pyrimidine bases. The unique Ultra IBD
stationary phase is composed of a polar group within, or
intrinsic to, an alkyl chain. The polar group gives extra
retention for many polar analytes as well as unique selectiv-
ity, a very high level of base deactivation, and compatibility
with highly aqueous mobile phases. The Ultra IBD column is
ideal for LC/MS because it often can resolve acidic, basic,
zwitterionic and/or neutral compounds in a single analysis
using simple mobile phases.
Figures 3 through 7 each show separations of one of the
major purines or pyrimidines from its respective ribonucleo-
