How strong is the influence of temperature for my pH calibration?
Temperature plays an important role as regards sample and buffer pH and an electrode's characteristics. The temperature dependency of the buffers is fully known and is shown on the buffer itself. The values on the following slide are just an example for standard pH buffers. Please check with your own buffer solution.
Regarding the electrodes, compensation will be made for the influence of temperature on the slope by the DASGIP PHPO amplifier modules. On the other hand, no compensation can be made for the pH shifts caused by altered reference potentials. If possible samples, buffers and electrodes should all have the same temperature.
