LC Columns

Shim-pack Arata LC columns from Shimadzu Scientific Instruments enable operators to achieve unprecedented peak shape of basic compounds while still maintaining good peak shape for acidic compounds, even when low-ionic-strength acidic mobile phase is used. Users can also achieve good peak shape and separation performance for peptides using the columns, even with weak ion-paring acids such as 0.1% formic acid containing mobile phase. In addition, the column solves the problem of TFA causing ion suppression in LC/MS analysis. The column also addresses poor peak shape and long equilibration times when analyzing basic compounds on a typical ODS column with low-ionic-strength acidic mobile phase.
