Robotic Analysers (SKALAR)
BOD analysis is the most common applications for water laboratories. The test is used as an indication of the organic pollution of water.
COD analysis is commonly used to determine the amount of organic pollutants found in surface water and wastewater. The COD value is a useful indicator for measuring the water quality.
Skalar's BOD analyzer is one of the most flexible platform available today. Besides the modern design and latest technological innovations, it can be configured from 18 up to 198 BOD bottles. The analyzer is developed to fit your exact laboratory requirements with respect to sample throughput, level of automation, sample capacity etc. Analyses are carried out with all major national and international regulations such as EPA 405.1/ISO 5815-1/ EN-1899-1/2, Standard Methods 5210 B, DIN 38409 etc. as well as customer specific methods.
COD (ISO 15705/EPA 410.4)
The automation of this method is based on exactly the same reaction as the classical method, but instead of titration, a photometric detection is used. All the manual handling steps are automated. An advantage is the use of pre-prepared tubes, minimizing handling of toxic and hazardous reagents. The analyzers can be used with commercial available or self-made COD reaction tubes and is compatible with several photometers.
COD by titration (ISO 6060)
The analyzer can be configured with 4-6 interchangeable sample racks, each with 20 positions. The samples can remain in the same vials from digestion to titration, thus preserving sample integrity. The analyzer is equipped with a titrator, burette tip, probe and stirrer. For range expansion without changing the burette, the platform can be configured with two titrators.
