Problems solved by technology

Although the electrochemiluminescence behavior has been observed in these systems, it is difficult to detect the electrochemiluminescence wavelength of the sample because the current electrochemiluminescence detector does not have the ability of wavelength resolution, which is not conducive to the optical behavior of electrochemiluminescence materials. research and its application
[0003] The current fluorescence spectroscopy technology is very mature, but the fluorescence spectroscopy technology alone can no longer meet everyone's needs. Combining the fluorescence spectroscopy technology with other technologies can not only achieve technological breakthroughs, but also expand the research field of fluorescence spectroscopy technology, greatly Increased utility of fluorescence spectroscopy
