(A) A series of 26 GSH injections (200 μM GSH) using the on-chip injection setup with the detection potential held at +0.1 V vs. Ag/AgCl. Sample flow rate held at 1.5 μL min−1 and the buffer flow rate held at 2.5 μL min−1. (B) A representative concentration curve using the on-chip injector for GSH (r2 = 0.9973).
