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 ...

TOC Analysis of Sewage Water to Prevent Covid-19 Transmission
What is TOC Analysis? Total Organic Carbon (TOC) Analysis is a measure of water quality. TOC is the amount of carbon that is found in an organic compound. It has become an important indication of approximate levels of organic contamination and can therefore be used as a suggestion of water quality. In many cases, TOC analysis is used as an on-going monitor of change or lack of change in organic ...

TOC Analysis of Bottled Water Using the Fusion UV/Persulfate TOC Analyzer
Abstract This application note demonstrates the Teledyne Tekmar Fusion UV/Persulfate analyzer’s ability to measure low levels of TOC in five popular bottled water brands. Bottled water samples varied in source and purification methods including: two natural aquifers, one vapor distilled, one reverse osmosis, and one two-stage microfiltration/UV light disinfection. All results had a 10% ...

NDIR CO2 Sensors
NDIR CO2 Sensors have evolved over the years from mercury-based manometers to large, bulky NDIR technology to the smaller, much more suitable CO2 sensors for modern solutions. This article explores what an NDIR Sensor is, why they are needed and in which industries they are useful as well as suggesting Edinburgh Sensor products to meet your CO2 sensor requirements.What is an NDIR CO2 Gas ...
