Microporous pre-reaction and immunochromatography combined pesticide residue detection device

Abstract

The application discloses a kind of micropore pre-reaction and pesticide residue detection equipment of immunochromatography, belong to pesticide detection technical field, including shell and for raw material processing processing mechanism, shell is provided with for the pesticide residue of raw material detection detection mechanism and for the replacement of detected liquid replacement mechanism;The application is by integrating units such as broken jar, reference liquid jar, liquid pump and feeding pump in shell, constructs the automatic sample pretreatment system, when detecting, fruit and vegetable samples are broken in broken jar, equipment is pumped into special reference liquid by pH7.2-7.6 phosphate buffer solution, Tween-20, NaCl and gelatin, the reference liquid not only can efficiently extract nicotinamide pesticide in fruit and vegetable, more importantly, its mild component can effectively eliminate the interference of fruit and vegetable matrix to subsequent immune response, while protecting the biological activity of colloidal gold labeled antibody, lay foundation for subsequent high specificity binding, improve the accuracy and reliability of detection.
