The ASTREE Electronic Tongue from Alpha MOS, like the human tongue, performs a global analysis (fingerprint) of a complex dissolved organic or inorganic compounds mixture.
The sensor head (7 cross selective sensors) dips into the liquid sample to be tested. Recording of the sensor output is performed within 2 minutes and then analysed by a chemometric software using multivariate statistics.
The ASTREE Electronic Tongue has a similar or better detection threshold for all the basic tastes, compared to the human tongue...
