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.
