a The variation in flow rate is measured when the nominal flow rate is established for the portable (‘Portable’) and compared to that of a commercial HPLC (‘Lab’ - Agilent 1260/90 system; Agilent, UK). b Profile of the change in flow rate when the pump is switched on and during a chromatographic run. The black arrowheads indicate valves switching to (i) loading and (ii) injection on the portable (‘Portable’, green line) and (iii) loading and (iv) injection on the Agilent system (blue line).
