Abstract

A collaurum test-paper counter used for detecting residue is prepared for fixing collaurum test-paper in test paper insertion slot and placing prepared test paper into case, fixing 1-2 of light source and a focusing lens as well as an electric charge coupler at proper positions in said case, connecting electric charge coupler to monolithic computer being connected separately to display and light source as well as CCD driving circuit, and connecting output end of CCD driving circuit to input end of electric charge coupler.

Description

technical field [0001] The invention relates to a device for detecting residues of pesticides, veterinary drugs, biological toxins, etc., in particular to a colloidal gold test strip reader for residue detection. technical background [0002] Because the detection sensitivity and specificity of colloidal gold test strips are much superior to those made by the original acetylcholinesterase technology, and in addition to being easy to store and use, it has been used in the detection of pesticides, veterinary drugs, and biotoxin residues in recent years. Colloidal gold test strips have developed rapidly and can detect more than 20 kinds of chemical substances. However, it is difficult to promote at present. One of the reasons is that it is difficult to determine the detection limit by visual inspection results. Due to individual differences, different conclusions may be drawn from the same result. Contents of the invention [0003] The present invention uses the photoelectri...
