(A) TIC (upper) and RIC (lower) of 50 μM cAMP (m/z = 328) sample droplets infused at 200 nL/min with FC-72 as oil phase, showing noisy signal all over the chromatogram and little signal of samples. (B) TIC (upper) and RIC (lower) of the same cAMP sample droplets with PFD as oil phase, showing discrete segmented signals of cAMP sample plugs.
