A detection system with the CL light guided from the reaction tube to the photomultiplier tube using a one millimeter glass optical fiber was developed and assessed. A linear response was observed using a semi-logarithm calibration between 50–2000 µM hydrogen peroxide with 1 µM as the limit of detection.engChemiluminescenceFiber opticsLuminolSilica nanoparticlesjournal article10.1080/00032711003731456
