Habekost A.Habekost@t-online.de 1 University of Education Ludwigsburg, Ludwigsburg, Germany Processes at electrodes can be monitored simultaneously electrochemically and spectroscopically. In electrochemical science, expensive equipment is needed to study these spectroelectrochemical processes. Because of the high price of these instruments, they are often not used in university education. Several experiments of three chemiluminescence systems with low-cost instruments are presented and partly compared with the expensive setups https://pubs.sciepub.com/wjce/11/4/4/wjce-11-4-4.pdf electrogenerated chemiluminescence low-cost spectroelectrochemistry
