Abstract
The claimed subject matter is directed to a continuous passive temperature, pressure, modulus of elasticity, and force compensated oscillating inertial microbalance and method of using the same. Temperature and/or pressure and/or modulus of elasticity compensation and/or force compensation is achieved by providing two substantially similar oscillating elements wherein only one oscillating element is subjected to the particulate collection means. The other oscillating element is subjected to all other factors but does not include a particulate collection means. By taking the difference between the two similar oscillating elements one can substantially remove the undesirable side effects having to do with changing temperature and/or pressure and/or modulus of elasticity. The ratio of the major axis to the minor axis is important to minimize precession of the oscillating elements.
