In environmental chemistry, the Chemical Oxygen Demand (COD/BOD) test is a widely used method to indirectly quantify organic compounds in water. The L800 is a specialized online analyzer designed to accurately determine true COD/BOD values in water samples, in accordance with standard methods. Utilizing UV absorbance/fluorescence spectroscopy across a full spectrum range (180-720nm), the L800 delivers precise, selective, and real-time measurement of COD/BOD levels.
