Infrared Spectroscopy Application in the Determination of Oil Content in Anhydrous Liquid Ammonia
Driven by the rapid expansion of solar cells, LCDs, LEDs, and semiconductor IC industries, demand for ultra-high purity ammonia continues to rise, with increasingly stringent purity specifications. Accordingly, ultra-pure ammonia producers also require significant volumes of anhydrous industrial ammonia as feedstock. Oil content is a critical quality parameter for feedstock evaluation and is therefore an important control item in production. Quantitative determination of oil content in liquid anhydrous ammonia can be achieved using infrared spectroscopy with a standard calibration curve method.
Infrared Spectroscopy Method’s Application in the Analysis of Acetaldehyde Content in Gasoline (Petrochemical Energy)
Infrared Spectroscopy provides a rapid, accurate, and non-destructive analytical approach for monitoring trace oxygenated compounds in complex hydrocarbon matrices. In the petrochemical and energy industries, the determination of acetaldehyde content in gasoline is of significant importance, as it is closely related to fuel quality, stability, and environmental performance. Compared with conventional chemical or chromatographic techniques, the IR spectroscopy method offers several advantages, including minimal sample preparation, reduced analysis time, and suitability for routine on-line or laboratory quality control applications.
Infrared Spectroscopy Application for the Detection of Fatty Acid Methyl Ester Content in Middle Distillate Oil
With the increasing challenges of energy scarcity and environmental pollution, there is growing demand for sustainable alternatives to conventional fossil fuels. One effective approach is blending biodiesel (B100) into mineral diesel (middle distillate fuels), which helps alleviate petroleum diesel supply pressure. However, variations in fatty acid methyl ester (FAME) content directly affect key fuel properties such as heating value, cetane number, and flash point, thereby influencing overall fuel quality and engine performance. Therefore, accurate control of FAME content in middle distillate fuels is essential. Infrared (IR) spectroscopy provides a reliable and efficient method for both qualitative and quantitative determination of FAME content in biodiesel-blended fuels, enabling effective quality control in fuel production and blending processes.
Infrared spectroscopy application in the determination of mineral insulating oil and lubricating oil structural composition
Mineral oils are refined petroleum-based liquid insulating materials composed primarily of alkanes, cycloalkanes, and aromatic hydrocarbons, which exhibit favourable electrical properties and oxidation stability. By controlling the relative composition of these hydrocarbon groups, different functional oils such as transformer oils, switchgear oils, and various lubricants can be produced. For example, aromatic hydrocarbons enhance gas absorption and are suitable for cable and capacitor oils, while cycloalkanes contribute to lower pour points, making them ideal for low-temperature lubricants. Infrared (IR) spectroscopy provides a rapid and accurate method for qualitative and quantitative analysis of hydrocarbon structural group composition in oils, supporting efficient quality control and product optimization.
Infrared Spectroscopy Method’s Application in the Detection of Non-typical Additives Content in Gasoline
Non-conventional gasoline additives, including aniline compounds, sec-butyl acetate, methylal, and dimethyl carbonate, are sometimes used to modify fuel combustion characteristics and improve anti-knock or antioxidant performance. However, these additives and their combustion by-products may adversely affect human health, environmental safety, and engine performance. The FTIR-7600S Infrared Spectrometer provides a rapid and accurate method for the determination of typical non-conventional additives in gasoline. The technique offers simple operation, high precision, and reliable analytical performance, making it suitable for routine fuel quality monitoring and regulatory inspection.
