Problems solved by technology

[0002] Immunoaffinity chromatography is a SPE technology that uses the specific reversible binding characteristics of antigens and antibodies. According to the high selectivity of antigens and antibodies, target compounds are extracted from complex samples to be tested; it has high selectivity and high affinity, At present, it is more and more widely used as a pretreatment purification method in the analysis of mycotoxins, veterinary drug residues, and some trace vitamin content. The use of actual detection work needs to be improved urgently

Abstract

The invention discloses a terbutaline, salbutamol, ractopamine, clenbuterol online immunoaffinity purification detecting device. Automatic sample loading and elution of immunoaffinity columns are realized through flow switching of three six-way valves; secondary enrichment purification and desalination are realized by the use of MCX columns; a purification solution can be directly introduced intoa tandem mass spectrometry detector, therefore, high-sensitivity detection of the four drugs based on automatic purification is realized. The immunoaffinity purification columns of the terbutaline, salbutamol, ractopamine, clenbuterol online immunoaffinity purification detecting device can be reused, and the automation of sample purification and analysis are realized, which can save money, save time, and save manpower; and the practicability is good.

Description

technical field [0001] The invention relates to food pretreatment, in particular to an on-line, reusable immunoaffinity purification device capable of purifying terbutaline, salbutamol, ractopamine and clenbuterol in animal-source food. Background technique [0002] Immunoaffinity chromatography is a SPE technology that utilizes the specific reversible binding properties of antigens and antibodies. According to the high selectivity of antigens and antibodies, target compounds are extracted from complex samples to be tested; it has high selectivity and high affinity, At present, it is more and more widely used as a pretreatment purification method in the analysis of mycotoxins, veterinary drug residues, and some trace vitamin content. The use of actual detection work needs to be improved urgently. Contents of the invention [0003] The object of the present invention is to aim at the defects and deficiencies of the prior art, to provide a simple in structure, reasonable in...
