TOC System Suitability Test for Sterile Water
The United States Pharmacopeia (USP) specifies that total organic carbon (TOC) content be used for management of organic impurity values permitted in bulk purified water, water for injection, in addition to sterile purified water and sterile water for injection. According to USP, TOC analyzers to be used for sterile water must satisfy the TOC system suitability test using test water having a ...

TOC analyzer for airports
During winter, de-icing processes at airports necessitate storm water and de-icing water management. Especially due to adhesive (sticky) substances, strongly fluctuating concentrations and a lot of chemicals, the monitoring systems itself must be tailor-made to fight this water analysis challenge. LAR 's QuickTOCairport is an application-specific online total organic carbon (TOC) analyzer that ...

Analyzing Total Organic Carbon in Sea Water
Abstract The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs. Laboratories are continually looking to increase sample throughput, decrease overall cost of ...

TOC Analysis by the Teledyne Tekmar Lotix Solids Sampler in a Variety of Matrices
Abstract The analysis of Total Organic Carbon (TOC) in samples can be difficult due to the variation of matrix types. Soil samples like sand, clay, and humus types can have erratic amounts of water, particle size, minerals, salt, and a large array of different materials depending on the collection location. The new Lotix Solid Sampler (LSS) Module used in conjunction with the Lotix ...

Total Organic Carbon Analysis for Purified Water and Water for Injection
Abstract In pharmaceuticals, water, specifically Purified Water (PW) and Water for Intravenous Injection (WFI), is vital for drug preparation. Producing and ensuring the cleanliness of this water entails very strict quality control and precise analytical testing methods. The United States Pharmacopeia (USP) and Japanese Pharmacopeia (JP) have promoted Total Organic Carbon (TOC) analysis as the ...

Surface waters have varying levels of organics that originate from both natural and anthropogenic sources.
These organic compounds can cause challenges for the water treatment plant by increasing coagulant demand, causing taste and odor issues and increasing demand for disinfectants. Even when the organics themselves are not a health hazard, when combined with chlorine they may lead to the formation of harmful disinfection byproducts (DBPs). Reducing the concentration of organics via various treatment ...

Simplifying the Process: Automated Pharmacopoeia Testing of Purified Water and Water for Injection
Abstract The requirements for Total Organic Carbon (TOC) analysis of Water for Injection (WFI) and pharmaceutical purified water (PW) are provided for in monographs of the United States Pharmacopoeia (USP) and European Pharmacopoeia (EP). The principle behind these methods is to challenge the instrument oxidation efficiency by comparing the recovery of a standard solution (rs) and the system ...

Real Time TOC Analysis in Steam and Condensate
Executive Summary Steam in petro/chemical plants could be contaminated with hydrocarbons (TOC = Total Organic Carbons) from various sources. In any case this is a sign for defects in the process, whether it they occur in the heat exchanger, the blow down vessel, the condensate recovery or other parts of the system. Conventional solutions to monitor such contaminations use TOC- analyzers that ...

Measuring TOC in Brine Solutions
In the chlor-alkali and electrolysis industries, as well as many others, there is a need to analyze for TOC in samples containing high salt concentrations. These samples can range from sea water, which is typically 3% salt, up to brine solutions containing 28% salt. Shimadzu’s TOC-L with the high salt kit (P/N 638-93176-01 for N model & P/N 638-93176-02 for H model) is well suited for ...

TOC Analysis of Turbid Liquid Waste Using the Teledyne Tekmar Lotix with LSS Boat
Abstract The analysis of Total Organic Carbon (TOC) in samples can be difficult due to the variety of sample matrices. Specifically, liquid samples with large particulates can negatively affect TOC instrumentation by blocking liquid-handling system valves and tubing and can lead to significant consumable costs and maintenance downtime. Considering these challenges, Teledyne Tekmar has developed ...

Raw water intake monitoring - Case Study
The Situation Hydrocarbons in municipal water supplies, including fresh water and desalination systems, are commonly limited to less than 1 part per million. Surface water from rivers, lakes, or the sea with marine traffic, nearby pipelines, or regular flooding can be contaminated by hydrocarbons. Freshwater treatment systems can be damaged by hydrocarbons or allow them to pass through ...
