What kind of electrophysiological experiment is illustrated in the recordings depicted below?

4. Compare the copper 2+ ion concentration in the eluent after 15 and 30 minutes to the copper 2+ ion concentration in the wastewater tank at the 15- and 30-minute mark. Single Pass Recovery is defined as: SPR = Cin-Cout Cin x 100 Where: Cin= copper concentration entering the EMR cell Cout= copper concentration leaving the EMR cell (4-1) The EMR cell has a total volume capacity of 12 Liters. In Run 1, at a flow rate of 0.8 LPM, the Single Pass Recovery Time would be: (12 Liters/0.8 LPM) = 15 minutes. From your analysis of the copper concentration of the eluent after 15 minutes and assuming Cin= 100 ppm copper, calculate the SPR for this EMR cell for Run 1.
