In order to meet the requirement of the signal acquisition of the quartz sensor arrays

the micro analysis system based on virtual instrument is designed.The hardware of the system is made up of oscillation circuit

data acquisition card and computer

while The soft module is designed by LabVIEW.The relation between the conductivity of the solution and the frequency response of the quartz sensor is analyzed.Experiments indicate that this system can detect the real-time frequency

and the results can be collected

processed

stored simultaneously;So it’s suitable for the further detection of biomacromolecules.
