The Cadenza CD-C18 HT 3 micron column shows comparable resolution to a sub-2 micron column, with much lower pressure.
The Cadenza CD-C18 HT 3 micron column shows better resolution between isopropylparaben and propylparaben than a sub-2 micron column, and the CD-C18 HT column also shows a higher plate count.
The Cadenza CD-C18 HT 3 micron column shows lower pressure, higher plate count, and higher resolution than a sub-2 micron column.

siRNA
Ribonucleic acid (RNA)
Double-stranded DNA fragments
Plasmid DNA
DNA from salmon spermary
Adenosine Phosphates (AMP, ADP, ATP)
Cadenza CW-C18 and Cadenza CL-C18 have different selectivities for double-stranded DNA. CW-C18 is a wide pore column that elutes the molecules earlier than the CL-C18, which is selective via its exposed silanol groups.
Unison UK-Amino separates mononucleotides of similar structure. For example, dGMP and GMP are resolved even though they differ in only a single hydroxyl group.
Separation of highly polar nucleic acid bases in normal phase mode due to high organic solvent density.
Aqueous normal phase separation of nucleosides using a silica column.
In comparison with the 500mm column, our 3um 250mm separates with high efficiency.
Analysis of purine nucleotides under LC-MS conditions.
Comparison of internal diameter in the reverse phase separation of oligo nucleotides.
Comparison of 5um column separation of nucleic acid bases. Unison US-C18 demonstrates excellent performance.
Comparative elution between stationary phases in ammonium acetate.
Separation of nucleotides used to rate freshness in seafood.
Separation of inosinic acid, a flavor enhancer.
High-speed separation of adenosine nucleotides.
