  • Percent Aromatics in Gasoline #3008

    The aromatic content of gasoline determines many of its combustion properties. Since it also impacts the environmental characteristics of the fuel it is desirable to have accurate measurements of this parameter. The traditional analytical method for measuring aromatics is either gas chromatography (GC) or an older method entitled fluorescent indicator adsorption (FIA), both of which are time and labor intensive. This note will discuss the use of Guided Wave hardware and software tools for the measurement of % aromatics in fuel products using fiber optic-based, Near-Infrared (NIR) spectroscopy. NIR can be applied in real time directly in process monitoring or as a laboratory procedure. In either case NIR is a time and money saving alternative to traditional methods.

    Analysis of Methylimidazoles in Caramel Colored Carbonated Beverages

    Caramel colorings are used as additives in a broad range of food and beverage products to impart a desired color, but have no nutritional or preservative function. Recently, the potential hazard to humans of ammonia- and ammonia-sulfite-process caramel colorings was raised, because they contain the by-product 4-methylimidazole, which is a potential carcinogen.1 The methylimidazole compounds are difficult to analyze due to their polar nature and low molecular weight. Traditional reversed phase techniques are unsuccessful in retaining these small polar compounds. Therefore, most HPLC methods utilize ion-exchange resins for analysis. Another common method involves GC analysis after the analytes first undergo a derivatization step. The purpose of the work shown in this article was to develop a simple and fast analytical method to determine the levels of 2-methylimidazole and 4-methylimidazole in caramel colored carbonated beverages.

    Analytical and measuring instruments of chemical and petrochemical

    In the chemical field, ICP-AES is used for a broad range of analysis in order to manage trace amounts of hazardous metals in the manufacturing process, manage additive elements essential to the functionality of a product, and manage the environment of the entire factory. Therefore, it is desirable to have a robust, highly stable system able to reliably accept the injection of a broad variety of samples, regardless of the type of solvent (aqueous/organic) or the presence of matrices. It is also important to simplify processes and reduce costs, which enhances the productivity of daily quality control work.

    Measurement solution for acrylates speciation

    A customer had a requirement for continuous Ethyl Acrylate monitoring. The process operations emit multiple Acrylate species, all at low concentrations, but only Ethyl Acrylate being reportable to the EA under the terms of the IPC permit. A 204M FTIR analyser was deployed and a chemometric model was built specifically to target Acrylates, with the purpose of separating and accurately quantify the target Ethyl Acrylate species.

    AutoChem - Process Analytical Technology (PAT)/Quality by Design (QbD)

    Process Analytical Technology (PAT) has been implemented for years, particularly by the chemical industry for the control of chemical processes. More recently, PAT has become a cornerstone of the US Food and Drug Administration’s (US FDA) Quality by Design (QbD) initiative for both the design and control of quality processes. For this reason, the pharmaceutical industry is also active in utilizing PAT tools. PAT tools can be implemented in both the lab and the plant, with laboratory PAT focused more on the design of a quality process and with plant PAT focused on the monitoring and control of the process.
