An in-depth examination of Total Organic Carbon (TOC) in the Pharmaceutical Sector
The pharmaceutical sector is among the most strictly regulated segments in the industry around the world. Since the primary concern of the sector is the safety of human beings, all the activities related to the manufacturing and formulation of medicines are observed and audited thoroughly by regulatory agencies like the FDA. One important aspect of pharma manufacturing is analysing the levels of Total Organic Carbon (TOC) in water and other process fluids. So in this blog post, we are going to kind of dig into what TOC actually is and why it matters so much in pharma manufacturing.
1. Definition of Total Organic Carbon (TOC)
The definition of TOC is the sum of organic carbon that is present in a sample. The source of organic carbon could be different, but organic carbon can come from algae, bacteria, and other organic materials. While producing pharmaceuticals, organic carbon can be used for the detection of microorganisms. The presence of such organisms can be dangerous for humans because of their possible negative impact on the product. Therefore, TOC is an important parameter to consider in pharma manufacturing.
2. Why is TOC important in pharma manufacturing?
Pharmaceutical manufacturing processes rely heavily on the use of water and other process fluids. Any contaminants present in these fluids can be introduced into the final product, making it potentially unsafe or ineffective for human use. The TOC analysis plays an essential role in pharma manufacturing processes since it facilitates ensuring the purity of the process fluids which get into contact with the drug substance. Through the regular monitoring of TOC concentration levels, manufacturers are able to detect and handle possible contamination threats and hence reduce the risk of problems.
3. How is TOC measured in pharma manufacturing?
TOC is measured by a variety of methods, from wet-chemical oxidation to combustion-oxidation processes. In pharma manufacturing, the most commonly used method is the combustion-oxidation method. The technique requires combustion of the sample at high temperatures, and then measurement of the amount of carbon dioxide generated. The quantity of carbon dioxide that is generated is directly related to the quantity of organic carbon found in the sample. TOC analysers of today utilize modern technology to determine TOC concentrations with precision and speed.
In conclusion, Total Organic Carbon (TOC) is an essential parameter to consider in pharma manufacturing. The presence of microorganisms in process fluids can be a significant risk to human safety and product quality, making it critical to monitor and maintain consistent levels of purity in process fluids. Combustion oxidation is the most widely employed technique used to determine the TOC concentration in pharmaceutical manufacturing. With today’s sophisticated TOC analysers, this has become easier than ever before. With the increasing regulatory requirements in the industry, it becomes more important for manufacturers to be aware of the current techniques in TOC analysis.
