You can work in direct injection mode or with a trap column. PharmaFluidics now offers their own µPAC™ trap column that is fully compatible with our analytical µPAC™ columns. We do have customers that use classical trap columns in conjunction with our µPAC™ columns. Nevertheless, such configurations can influence the performance of our analytical columns because, in general, conventional trap columns have slightly different retention capabilities compared to the µPACᵀᴹ columns.
Related questionsIs it possible to reduce the length of the capillaries that connect the µPAC™ column to obtain better separation results?
