The Controlled Environment Cell</B> is used in the development of
electronic noses, the study of polymer-vapor interactions by
impedance and dielectric spectroscopies, and as a volatile
organic compound (VOC) sensor. The Controlled Environment Cell is
used for performing AC electrical impedance and DC conductance
experiments under controlled gas/vapor environment conditions.
The design is similar to that used in the laboratory of Prof.
Mark Wrighton to study the electrical impedance changes in
electropolymerized polyaniline films upon exposure to varying
humidities. This design has also been used by scientists at ICI
Chemicals to study acid-base interactions (by electrical
impedance spectroscopy (0.1 mHz - 60 KHz)) of various probe
vapors (water, acetone, chloroform, methanol) with ultra thin
polymer coatings.</FONT></FONT></BLOCKQUOTE>

</FONT>The Liquid Flow Cell Detector (FCD) </B>is used as an
electrochemical detector (ECD) in Liquid Chromatography (LC) and
Flow Injection Analysis (FIA) applications. The interdigitated
electrode format of the flow cell sensor chip allows use of the
ECD in amperometric generator-collector mode or electrochemical
impedance mode. Both modes offer very high selectivity based on
the redox properties of the analyte to be measured and very high
sensitivity -- down to picogram levels for its limit of
detection. A wide variety of ionic and non-ionic compounds may be
readily detected by ECD, thus making ECD a highly versatile
detection technique. Similarly, conductance detection is integral
to Ion Chromatography (IC) and Flow Injection Analysis (FIA)
where conductance changes in the range from 0.1 S to 10 mS may be
readily measured usiung the Flow Cell Detector.</FONT></FONT></BLOCKQUOTE>

Conductance measurements may be used in Ion Chromatography. The
IME 1010.3 FD LC sensor is also used in materials science
research of electroactive polymer films. Polymer films that are
spun cast, electropolymerized, or coated onto the LC sensor may
be analyzed by AC Impedance, DC pulse amperometry, or by using
the EPSIS (The Electroactive Polymer Sensor Interrogation System)
in a flowing stream. Changes in electrical impedance or
conductivity of the film could then be monitored in response to
various ionic analytes, or redox active analytes. </FONT></FONT>

electroactive polymers. The interdigit space may likewise be
