Abstract
A molecular contamination monitoring system includes a piezoelectric measurement sensor exposed to a molecular constituent to be measured; a piezoelectric reference sensor; and a filter for filtering said molecular constituent, the filter located between the reference sensor and the measurement environment. The reference sensor is exposed to the same ambient conditions of temperature, pressure and humidity as the measurement sensor. Alternatively, there may be a plurality of different reference sensors having different filters, or there may be a plurality of different measurement sensors.
