Hi Hosein Afshary,

If you are using biologic EC-lab software, then you can try constant voltage technique in Modulo Bat program. You can set the limit of the step as time. For more information see the page 142 of the document.

Thanks Shubham Kaushik for your answer.

I use "Dropview" but I will try the technique anyway as there are some similarity in all softwares.

Thanks again.

I suggest you to use chronoamperometry to obtain time vs ECL intensity stability test.

Thanks Dr. Venkateswara Raju Chikkili for your answer.

I did that. The name of the method on potentiostate was "pulsed chronoamperometry".

Dear Hosein Afshary

I am using Autolab potentiostat (NOVA software). We have chronoamperometry with different step applied potentials. the following options we have.

step 1: 0V

time: 10s

step 2: 1.2 V

time: 0.5 s

number of repetitions: 30

Thanks again Dr. Venkateswara Raju Chikkili for your useful answer.

You are most welcome Hosein. You can ask any ECL related questions.
