Danish mass spectrometer can be divided into true and false green food

A lab in Roskis, Denmark, invented an air conditioning unit with a mass spectrometer.
The device can draw the relative content of more than 60 elements in agricultural products, and can be compared with mass spectrometry maps of agricultural products samples, so as to know whether these agricultural products have chemical fertilizers and pesticide residues, and confirm whether it is free of chemical fertilizers and pesticide residues. True green foods can now identify counterfeit green food from traders in the circulation field.
