• Analysis of Additive Elements, Wear Metals, and Contaminants in Used Lubricating Oil According to ASTM D5185: ICPE-9820

    Analysis of lubricants added to engine oils such as those used in automobiles and ships is an effective as well as important way to diagnose the state of the engine and other equipment. According to ASTM International Standard D5185 1), inductively coupled plasma (ICP) atomic emission spectrometry with organic solvent dilution is specified for measurement of additive elements, wear metals and contaminants present in used lubricants.

  • Determination of Chemical Species in Marine Fuel Oil in accordance with ASTM D 7845 by GC-MS

     

    Fuel oil, also known as marine fuel oil, is a fraction obtained through petroleum distillation. Despite its widespread use in marine fuel pumps, contamination with compounds such as phenols has caused fuel pump malfunctions in recent years. ASTM D7845 provides standardized analytical methods for 30 aromatic and oxygenated compounds in marine fuel oil. In this article, the quantitation of aromatics and oxygenates in marine fuel oil was conducted as per ASTM D7845 using a Shimadzu GCMS-QP™2020 NX.

  • Shimadzu-Solutions For Lubricant Monitoring

    Lubricants are the lifeblood of mechanical engines and provide critical frictionreducing, cooling, and cleaning properties that are essential to their proper functioning and operation. Over time and throughout their use, lubricants degrade, and that functionality and those properties become inhibited. This degradation can cause mechanical problems and shorten the lifespan of an engine.
    Just as clinical analyses of human blood can diagnose health conditions, chemical analysis of lubricants ensures their performance and can indicate mechanical issues that demand attention, which is critical to the functioning of engines and motors. Particularly on large engines or turbines in which the volume of oil in the sump can be thousands of times greater than in a passenger car, routine monitoring of lubricants ensures optimal performance, minimizes costs, and can protect the engine. Shimadzu has all of the tools necessary for common lubricant analysis, including additives and degradation as well as fuel dilution, wear metals, and other contaminants.

  • Analysis of Additive Elements in Lubricating Oil According to ASTM D4951: ICPE-9820

    Numerous additives consisting of various types of organometallic substances are added to lubricating oils to enhance performance. It is important to manage the concentrations of these additives for the quality control of lubricating oils. Both ASTM D4951 of the ASTM International standards and JPI-5S-38-2003 of the Japan Petroleum Institute standards (Lubricating Oils - Determination of Additive Elements) specify the use of ICP atomic emission spectrometry with organic solvent dilution as the test measurement method for elements in additives. We performed elemental analysis of the additives in commercially available engine oil, automatic transmission fluid (ATF), and gear oil, using the Shimadzu ICPE-9820 multi-type ICP atomic emission spectrometer, after diluting the samples with an organic solvent.

  • Quantitative Analysis of 57 Fragrance Allergens in Cosmetics Using Twin Line MS System

    Under the European Cosmetics Directive (EC 1223/2009)1), 24 of the fragrances used in cosmetics are regulated as fragrance
    allergens. If a leave-on product contains more than 0.001 % or a rinse-off product contains more than 0.01 %, it must be labeled on the product. Recently, however, following an opinion by the Scientific Committee on Consumer Safety (SCCS), the number of regulated compounds has been scheduled to be expanded to more than 80. Therefore, manufacturers of cosmetics need to know exactly what fragrance compounds are contained in finished products orraw materials.

  • Measuring the Fluorescence Quantum Efficiency of Liquid Samples

    Fluorescent substances absorb a characteristic wavelength of that substance and then emit a fluorescent light with a wavelength longer than the absorbed light. The ratio of photons absorbed versus emitted as fluorescent light is referred to as the fluorescence quantum yield or quantum efficiency and is associated with the fluorescence intensity of fluorescent substances.
     
    This article describes using an RF-6000 spectrofluorophotometer with an integrating sphere attached to determine the fluorescence quantum efficiency and measure quinine sulfate.

  • Shimadzu - HPLC-033 Aromatic Hydrocarbons in Diesel Fuel LC-RID ASTM D6591

    The accurate determination of the aromatic content of fuels is critical to assessing their quality and combustion characteristics. These parameters are crucial to ensuring aviation safety and compliance with environmental regulations.
    This application news demonstrates the use of the Shimadzu HPLC for the determination of mono-, di-, and tri-plus aromatic hydrocarbon content in diesel fuels and middle distillates with boiling points in the range of 150°to 400°C in accordance with ASTM D6591.

  • Measurement of Microplastics and Use of Thermal-Damaged Plastics Library

    Microscopic plastic with a size of several μm to 5 mm or less is called microplastic. As a marine environmental problem that adversely affects coastlines and marine ecosystems, and consequently may potentially affect human health, microplastics have become a global issue in recent years. As early action is necessary to protect the global environment, various analytical devices are used to designate the sources of microplastics and study countermeasures.
     
    This article introduces measurement of microplastics with a size on the order of several mm and use of the Shimadzu thermal-damaged plastics library to identify the samples.
