Hi,
I'm an Electrical Engineering student and I got a part-time job in a life science institute.
They want me to do impedance spectroscopy on cell suspension.
I've got the LV driver for the SI1260 and I managed to draw a working program for data acquisition and a data correction procedure too.
But my experiments seam to go wrong. I have theoretical background but I still have some practical unanswered questions about the 4 point measurements technique.
So if someone is aware of the subject and willing to discus please drop a mesege here.
Thank you!

hello
what problems you have with four probe impedance spectroscopy measurements ?
I use EIS daily so maybe i can help you

The analyzer is recently calibrated and it should perform fine until 1MHz. This makes me think that there is a problem with my measure electrodes.
For curent electrodes I use chrome and for measure electrodes I have tried dental stainless steel, agar, carbon. I always have my electrodes recesed from the measurement chamber as described by Schwan.
