Photolytic rate of some critical reactant and free radical (O(1D), NO2, H2O2, HONO, HCHO etc.) are key indicators for identify status & extent of photochemical pollution.The analyzer is receiving solar radiation by quartz probe and transferring the radiation to spectrum via optical quartz fiber, the spectrum data will be evaluated and compared with reference data with mathematical approach and gives photolytic rate.
