For every test or method developed to identify and isolate toxins, a large amount of toxic waste is produced. Total Nitrogen is composed of four separate methods. All components that comprise total nitrogen “are biochemically interconvertible and are components of the nitrogen cycle,” and can occur in both wastewater and natural waters.

By using Shimadzu’s Total Nitrogen Module, a method that once took up to a full day to complete can now be completed in approximately 4 minutes. Total Organic Carbon can also be analyzed simultaneously, reducing analytical time even further, reducing long-term costs and allowing for a high sample throughput. In addition, by incorporating four separate methods into one, hazardous wastes and toxic chemicals are no longer necessary.
