Calcium electrode

The OROBOROS ISE system is designed with replaceable membranes so in principal you can measure TPP or Ca. At the moment we offer only TPP membranes, Ca will still take a few months.

You could help us in the development by explaining what you would like to do/ see in a Ca²⁺ experiment and what you expect from the electrode: what ca concentrations do you want to measure, Ca²⁺ release or uptake? what total concentration change in a 2 ml chamber (!) do you expect? Do you want to measure in a Ca buffered medium? (decreased sensitivity to changes) or without Ca²⁺ buffering but then how do you get to physiological Ca²⁺ concentration? Do you want to measure at physiological Ca²⁺ concentrations?.......

We have complied a short reading list that may be of interest to those planing to to do Ca²⁺ measurements. A special emphasis are references describing the preparation of Ca²⁺ calibration buffers.
