TOC-L Laboratory Total Organic Carbon Analyzers
Standalone or PC-controlled Combustion Analyzers


Functional Comparison of the TOC-L Series with Conventional Combustion Catalytic Oxidation Method TOC Analyzers

TOC-V System and TOC-L System

The TOC-L series provides even better functionality and operability than the popular TOC-V series. In addition, applications can be further enhanced by adopting new options such as a kit for small sample volumes and a high-salt sample combustion tube kit.
