At ZP we are often asked what is the accuracy of the ZP electrochemical sensors and biosensors, but the answer to the question is ‘how do you intend to use them?’. The accuracy of an electrochemical biosensor is a function of the sensor, your sample and your system in which you place the sensor.

 

The second question is how will your sensor work in my fluid, and these can range from: urine, blood, plasma, serum, saliva, breath, foods, beverages etc, a sub-question to this question is what will the drift be like. Again the answer to this questions is as above, and the way the sensor will respond to your sample depends on your sample and the degree of drift with time depends on the sensor, your sample and your system. In this note we do give a calibration routine that will allow you to compensate for drift and keep the overall system accurate.
