Yes, you can use a liquid junction. You will, however, need to connect the outlet union of the µPACᵀᴹ column to the liquid junction with a 360 µm O.D./20 µm I.D. fused silica capillary. Here, you can find information on the part numbers required for the union. This configuration is commonly-adopted at our expert centres and the additional connection between the column and the mass spectrometer neither results in any issues nor leads to any negative effects on the chromatography.
