Polymerization Inhibitors

Polymer chain growth may produce unwanted side reactions and/or unwanted auto-polymerization. The control of polymerization inhibitor concentration is necessary to drive the reaction towards a desirable outcome.

Ultraviolet-Visible Spectroscopty

Controlling polymer chain length during synthesis is typically achieved via the intentional addition and control of the inhibitor species. Low concentration levels of inhibitor may produce unwanted reactions, while high concentration levels can result in a lack of polymerization. The tec5USA online Ultraviolet-visible (UV-Vis) Analyzer monitors real-time concentration levels of targeted polymerization inhibitors, such as Cupferron. With millisecond acquisition time, rapid reactions such as unwanted auto-polymerization, are immediately identified and the process optimized as necessary.

    Typical applications include white light interference for thin film analysis, UV absorption of proteins for quantitative analysis, colorimetry, impurity detection in water, cleaning validation for API manufacturing, polymerization inhibitor monitoring, electroplating bath monitoring....

    The spectroscopic methodology is determined by which parameters are important to monitor during a process. For example, if you want to monitor protein concentration in a bioreactor, in which the biosynthesis takes place in an aqueous medium, then you likely would want to use Raman spectroscopy for the application, as water does not contribute to the Raman signal. Alternatively, if moisture content is important, water has very strong absorption in the NIR due to several vibrational and combination modes that can be monitored; water is transparent in the UV and visible spectral region. Understanding which chemical is important as there could be various factors that influence the choice of methodology....

    NIR spectroscopy is utilized across a variety of industries for qualitative and quantitative product analysis. Typical industries include Chemistry, Pharmacology, Food Feed & Beverage, Agriculture, and others. NIR spectroscopy is well suited for species containing C-H, N-H & O-H bonds, making it a wide-range technology for a variety of applications such as moisture, fat, oil, alcohol, APIs, polymers, etc....

    Raman spectroscopy is a technique which is used for several markets. These industries include Oil and Gas, Pharmacology, Biotechnology, Petrochemistry and many others. Due to the high selectivity of Raman spectroscopy, it is a powerful tool for many applications including, hydrocarbon analysis, bioreactor protein monitoring, crystallization monitoring, API concentration, polymer identification, surfactant analysis, natural gas components and several others....
