TOC Analyzer QuickTOCultra™

TOC Analyzer for the rough stuff

LAR’s TOC analyzer QuickTOCultra™ is the most reliable measurement system for the roughest wastewater applications. Due to an unrivaled injection and oxidation technique, the QuickTOCultra easily handles sticky, fatty, salty, and high-particle samples unlike other TOC analyzers.

The combustion leader in TOC analysis provides maximum reliability and availability, hence also profitability for its operators.

Online TRUE TOC for every kind of water. Especially for the rough stuff.

LAR’s QuickTOCultra is the ultimate online TOC analyzer for the determination of total carbon (TC), total organic carbon (TOC), total inorganic carbon (TIC) and dissolved organic carbon (DOC) suitable even for the most difficult wastewater applications.

Exact Analysis at 1,200°C, the TRUE TOC is determined.

For an exact TOC measurement all carbons bonds – incl. particles – must be reliably combusted. LAR’s unique robotic system is capable of transporting and measuring a high content of solid matter without any filtration of the sample. Additionally, LAR’s high temperature method with combustion at 1,200°C guarantees the complete oxidation of the sample.

This analysis results in TRUE TOC
