Errors in Chemical Sensor Measurements
... An analytical chemist performing tests of chemical sensors should be very conscious about possible sources of errors influencing the measurements. Some of them have chemical origin and as quite well predicted and recognised can be determined with the help of analytical methods (e.g. determination of ...
