WebbMethods such a s TOC or an alkalinity titration are generally considered nonspecific because, in most cases, there is more than one species that can contribute to the measured property. Being nonspecific does not mean that the method is unacceptable. WebbThe theory of constraints ( TOC) is a management paradigm that views any manageable system as being limited in achieving more of its goals by a very small number of constraints. There is always at least one constraint, and TOC uses a focusing process to identify the constraint and restructure the rest of the organization around it.

Total Organic Carbon (TOC) Analyzers and Parameter Overview

Webb(TOC) and Chemical Oxygen Demand (COD) are two methods used to determine the organic content in wastewater. However the COD-method produces dangerous mercury-containing waste products, and for that reason, the EU has decide to phase it out. TOC-analysis is suggested as replacement method.

Webb30 nov. 2024 · The methods used by our Optosky are high-temperature catalytic oxidation method, ultraviolet persulfate oxidation method, and conductivity method. Compared COD and BOD are laboratory techniques, while TOC can be done in the laboratory (offline measurement) or online (online measurement. Since all TOC analyzers only actually measure total carbon, TOC analysis always requires some accounting for the inorganic carbon that is always present. One analysis technique involves a two-stage process commonly referred to as TC-IC. It measures the amount of inorganic carbon (IC) evolved from an acidified aliquot of a sample and also the amount of total carbon (TC) present in the sa…
