Speciality RP Silica Columns
There are three specialty reversed phase TSKgel columns with silica base support: TSKgel ODS-120A, TSKgel 120T, and TSKgel OligoDNA-RP.
TSKgel ODS-120A columns use a 15 nm pore size silica base support. The silica's exclusion limit of 10,000 Da makes them a good choice for the reversed phase chromatography of peptides, small proteins, and environmental samples such as poly-aromatic hydrocarbons.
The "A" signifies that the material is not endcapped. For charged samples, the endcapped TSKgel ODS-120T column is a more suitable alternative.
TSKgel ODS-120T columns use a 15 nm pore size silica base support. The columns are endcapped with trimethyl silane groups to improve the peak shape of negatively charged analytes.
Specifically designed for purification of oligonucleotides, RNA and DNA fragments (up to 500mer), TSKgel OligoDNA RP can provide excellent separations of samples with very similar sequences.
