Skalar is continuously developing and integrating new automated applications for the San++ Continuous Flow Analyzer. Skalar’s most recent development is the implementation of the Kelada-01 (EPA) method for the determination of total cyanide, acid dissociable cyanide and thiocyanate. Determination of cyanide is regulated by ISO and EPA standards.
The ISO 14403 method describes the determination of total cyanide and free cyanide in various types of water. Skalar offers the complete system to perform cyanide determination according ISO14403. This method is based on UV digestion using a borosilicate irradiation coil and UV light source. In this way Total Cyanide is determined and break-down of thiocyanate is excluded. Free Cyanide can also be determined on the same module set-up by switching-off the UV-lamp. Thiocyanate can be analyzed simultaneously using a specific chemistry module.
The Kelada-01 method provides the determination of total cyanide, acid dissociable cyanide and thiocyanate in various types of water, using UV digestion and distillation in one reactor set-up. Kelada-01 is approved and adapted in the Federal Register, EPA 40 CFR Parts 122 & 136.
For both ISO and EPA regulatory methods Skalar can now offer a fully automated system for determination of cyanide species.By automating the complete test procedure from sampling to result, including automated UV-digestion and distillation the sample throughput is increased significantly for cyanide analysis.
- Both ISO and EPA methods require little or no manual sample pre-treatment
- The entire tests are performed on-line, 25-30 samples per hour
- Kelada-01 method is licensed to be used only on the Skalar San++ analyzer
With the EPA approved Kelada-01 and the ISO14403 methods Skalar completes its range of total CN methodologies in accordance with international standardized regulations.
