Apparatus and method for measuring the mass of a substance |
摘要 |
An apparatus for measuring the mass of a substance includes a sensor having a membrane layer, the membrane for receiving the substance thereon, an oscillator device for driving the membrane at a reference resonant frequency, a frequency detection device for determining a change in the reference resonant frequency caused by the presence of the substance on the membrane, and a mass determining device for determining the mass of the substance, the change in the reference resonant frequency being indicative of the mass of the substance. |
