Chemical Oxygen Demand (COD) is an important parameter for determining the amount of organic pollution in water.
Skalar’s SP10COD robotic analyzer has been designed for the cost-effective automation of the easy to use small-scale sealed-tube COD (ST-COD) analysis according to the ISO15705 and EPA 410.4. The ST-COD tube method is compared to the classical titration method, more user-friendly as there is no contact with hazardous reagents and more environmentally friendly, because less reagents are used. The test can be used for any aqueous sample, which includes all sewage and wastewaters.
The analyzer consists of a XYZ sample-handling station with a sample capacity of 104 tubes, a gripper for tube transportation, a thermo reactor with 104 positions for digestion, sample rack for sample loading and cool down, a photometer and a pc for data handling and control. The SP10COD can handle ready-made and self-made COD reaction tubes and is compatible with a range of different photometers. Higher capacity is possible on Skalar’s SP50COD robotic analyzer.
The SP10COD offers a real “walk-away” fully automated COD concept, including mixing, heating, cooling and photometric measurement.
