“Subtle light produced when a molecule transitions from an excited state to a ground state during a chemical reaction.” This method of detecting this light is called the chemiluminescence method. Chemiluminescence is a very faint light; thus, the measuring device must be more sensitive compared to other light detection devices.
Our Chemiluminescence Analyzer (CLA series) is a device that measures very faint light, invisible to the human eye. It can detect emissions from substances at the photon level (50 photons/cm2/sec, light at about 1/10,000 of the brightness of a firefly’s light, 10-14 watt level). It is one of the world’s most sensitive weak-light detection devices.
Detects oxidation deterioration with higher sensitivity than conventional methods.
A standard for measurement methods using the weak-light measuring device (Chemiluminescence Analyzer) has been determined by JIS (Japanese Industrial Standards) and ISO (International Organization for Standardization).
