COD in 10 Minutes

摘要

Camlab (UK) has launched a revolutionary instrument from Aqua Diagnostic, which is capable of accurate, sensitive, real-time analysis of Chemical Oxygen Demand. The new green technology requires no hazardous chemicals, produces fast results and eliminates the time consuming digestion step. The core of the technology is the PeCOD™ sensor which has a number of practical advantages compared with the traditional methods of COD analysis. PeCOD's ability to analyse samples containing chloride is significantly better than the dichromate method, and does not require the addition of toxic reagents like mercury and silver salts. The increased sensitivity of the method enables the measurement of clean water samples with low ppm levels of COD.
