Detector for detecting trace substance of fluid

Abstract

This is a tester to test the mini quantity materials in the fluid testament. This tester comprises sample room, the band pass filter plate, and two infrared detectors. The sample room is designed base to the principle of F-P interference its action is about to the resonance action of double pass ways filter plate. One of the two pass way's position is designed as the absorbed characteristic crest value position of tested fluid sample, the other pass way's position is designed as the non absorbed crest value position of tested fluid sample, it is consult crest position. According to the relative change of strengthen between two transmission crest to test out the contained quantity of the tested sample.

Description

technical field [0001] The invention relates to a detector, in particular to a detector for detecting trace substances in a fluid. Background technique [0002] With the development of society and the advancement of technology, people use chemicals and new materials more and more frequently. The number of chemicals registered in the American Chemical Abstracts alone has exceeded 18 million, and it is estimated that 100,000 have entered the environment. Many of them are poisonous and harmful substances that destroy ecological balance and endanger human health, and even carcinogenic, distorting and mutagenic substances that threaten human survival, and some substances have very low pathogenicity. can cause great harm to the human body. In addition, in order to diagnose antigens or antibodies such as bacteria, viruses, and spirochetes in infectious diseases, such as HIV antibodies in serum, ultra-trace active substances such as insulin, growth hormone, thyroxine, progesterone ...

Problems solved by technology

However, all the above methods are limited by the detection principle. The former can only detect those substances that can react with the markers, but can’t do anything for the substances that have no interaction with the markers. Most of the sensitivity is not high enough, and most of the substances to be tested have It is unknown whether the biological activity will change after reacting with the marker, or whether it can objectively reflect the characteristics of the substance to be tested; although the latter can achieve the purpose of enhancing the detection signal by increasing the mass of the substance to be tested, but currently It has not been possible to synthesize molecules with biological activity, so this method cannot completely and objectively reflect the characteristics of the biologically active substance itself
