Experimental setup used for the determination of the molar absorptivity ratios e1 and e3/e2. The microfluidic flow cells and vials with mCP solutions are submerged in a 15% ethylene glycol thermostated bath. The light is transmitted from the light source to the flow cells and to the spectrophotometer through 600 µm diameter optical fibres (Thorlabs, USA).
