What
a chemical sensor is expected to be
A chemical sensor is a self contained
probe that provides in real time information about the chemical composition
of its surroundings.
To this end, it has to perform two functions:
Recognition (sensing), which consists
of a specific interaction with a component of the sample (analyte). More>>
Transduction, which represents the ensuing
modification of a physical property, that can be converted into a measurable
physical signal (electrical, optical, etc.). The signal is further employed
for assessing the analyte concentration. More>>
An example: the glass electrode
is able to recognize the hydrogen ion by selective ion exchange and gives
rise to a membrane electric potential that is a function of hydrogen
ion concentration.
What a chemical sensor looks
like?
Advantages of chemical sensors
-
Substitution of standard analytical
procedures by fast detection and analysis using dedicated sensors;
-
Automation of the analysis and monitoring
of chemical quantities;
-
Field analysis by means of portable
instruments
Applications
-
Industry: process analytical chemistry;
-
Environment: automatic monitoring of
chemical pollution
-
Biomedical Science: fast and/or in
vivo monitoring of drugs and biologically important compounds (e.g.
O2, CO2 and glucose content in blood)
-
Food industry and Biotechnology: automatic
control of chemical parameters,such as pH, O2 and CO2
content, or nutrient concentration.
An application:
Measuring pH in meat
Measuring pH in slaughtered meat is
a good way to monitor product quality. A lance-shaped ISFET probe
(Sentron), with a large handle for good grip, is an ideal solution
for fast, accurate and most of all, safe measurements. More>> |
