Spanish agchem detector patent
A pesticide detector system has been granted a patent in Spain. Researchers from the Polytechnic University of Valencia (UPV) have developed piezoelectric sensors, allowing the detection in laboratories of pesticides and their metabolite residues in fruit or vegetable juices and in water. The major advantage of the device is the “increased speed” of detection compared with older “and [more] expensive” systems, the UPV says. It also allows measurements to be taken in the field without the need for qualified personnel. A complete test and detection cycle takes around 20 minutes and the device is “up to 100 times” more sensitive than comparable tools.
