Potentiometric response of the pulse-heated Cu2+ selective electrode inside a bulk solution kept at room temperature for: a) 0, b) 1, c) 5, d) 10, e) 50 and f) 100 nM of Cu2+, while applying 20 s heat pulses at 60 °C (heating voltage 3 V). The arrows indicate addition of Cu2+ ions to the bulk solution.
