在食品或生物组织中都存在的有机化合物几乎常被大气中的氧所氧化,结果造成产品质量或生物机能的变化。在氧化反应进行的同时,已经证明还普遍存在着化学发光的现象。近年来,由于光电子设备技术的发展,特别是高灵敏度光电倍增器,以及灵敏度高、测定简便的化学发光测定器研究成功,使测定极微弱化学发光(extra-weak chemfluminescence,CL)得以实现。 Organic compounds that are present in food or biological tissues are almost always oxidized by atmospheric oxygen, resulting in changes in product quality or biological function. While the oxidation reaction proceeds, chemiluminescence has also been shown to be widespread. In recent years, due to the development of optoelectronic devices technology, especially the high sensitivity photomultiplier, as well as the high sensitivity and simple determination of chemiluminescence detector successfully studied, the determination of very weak chemiluminescence (CL) can be achieved.
