TOC Evaluation of Ammonia Solution

User Benefits

- The total organic carbon (TOC) in 2 % ammonia solution can be determined directly without dilution, which is optimal for organic contamination management of ammonia solution. - By measuring inorganic carbon (IC), the contained carbon dioxide (CO₂) concentration can also be quantified. - Automatic analysis of multiple samples is possible, with the use of the auto-sampler ASI-L.

Introduction

Ammonia solution is widely used for various purposes in modern society, such as use as a laundry detergent, in cosmetics and pharmaceuticals, as well as for the treatment of nitrogen oxides (NOx) generated in thermal power plants and waste treatment plants. Furthermore, ammonia fuel has gained attention in recent years as a zero-emission fuel for realization of a decarbonized society. Various types of research on ammonia fuel are underway due to its lack of CO₂ emissions. To use ammonia solution in these applications, there is a requirement for high purity, so control of organic impurities is important. Using the Shimadzu total organic carbon (TOC) analyzer enables rapid and simple control of organic impurities in ammonia solution. This article introduces an example of TOC measurement of 2 % ammonia solution, using the Shimadzu TOC-L analyzer.
