Oi 1080

Total Organic Carbon (TOC) analyser

The 1080 TOC analyser allows the accurate, reliable processing of aqueous samples for analysis of total organic carbon (TOC), total inorganic carbon (TIC), and non-purgeable organic carbon (NPOC) content.

Superior Technology for Better Results

TOC analysis is a well-established analytical technique that provides important data relating to water quality. While combustion methods are very effective for the analysis of difficult to oxidise samples, those of high molecular weight and ones that contain large amounts of salt, these types of samples can be problematic for the equipment. Over time, they can take their toll on analysers, clogging the instrumentation and shortening injector life, leading to unreliable data, increased catalyst costs and substantial downtime required for equipment maintenance.

The OI 1080 TOC analyser however, is perfect for these particular samples. A high-temperature catalytic combustion oxidises and converts the organic compounds present in aqueous samples to CO2 for measurement by a solid-state, non-dispersive infrared (SS-NDIR) detector.

Meticulously engineered for reliability and ease of use, the 1080 Total Organic Carbon Analyser handles even the most challenging applications without the requirement for expensive additional modules.
