Qcm200 is a very sensitive mass detection instrument. Its measurement accuracy can reach the level of nanogram, which is 100 times higher than that of the electronic microbalance with the sensitivity of microgram. In theory, the mass change that can be measured is equivalent to a fraction of that of single molecular layer or atomic layer. The system is mainly composed of electronic oscillation circuit, frequency counter and piezoelectric quartz crystal
