| Abstract: | A computer controlled intelligent measurement and data acquisition system for piezoelectric crystal sensor array was studied. The function and structure of the hardware and the software for data acquisition were introduced. This instrument has high precision and stability. The number of piezoelectric crystal sensors measured can be varied from one to twelve. The on-line observation of frequency shift may be completed, and the data of fre- quency shifts can be saved for later treatment. This instrument provides a strong tool for mixture determination, complex substances classification with piezoelectric crystal sensor ar- ray or kinetic frequency signal observation for piezoelectric crysta1 sensor. It is of great use for analytical chemistry. |
