Organic Contaminant Monitor

Abstract:

Acoustic place mode (APM) devices are extremely sensitive to small mass changes at
their surfaces (ng/cm2) when immersed in liquids. Combined with a properly derivatized
surface, they are capable of detecting trace organic constituents in water. An APM
dence sensor with a plasma polymerized surface will be developed as a precursor to
an automated monitor for organic species in reconstituted water. The proposed sensor
is lightweight, extremely accurate, has low power consumption; and is highly durable
and reliable. Modification of the surface coating will create a family of sensors
for a wide variety of chemical species.
These devices will find a variety of applications in the electronic chemical and
medical industries where trace organic contaminants affect product quality. They
may also be used for monitoring organic contaminants on a ground water. When derivatized
with a different surface, they may be used to monitor a wide range of species in
water such as heavy metals.
