“…The relative determination error was 5.33% at the test concentration level x 0 = 3.33 wt% and RSD was 2.26% at the concentration level of x 0 = 9.54 wt%. Li Jingyan et al (2012) indicate that if the RSD is higher than 5%, the method is not acceptable for accurate measurement.…”

The paper presents the possibilities of detecting diesel fuel without rapeseed methyl ester (RME) in the concentration range of 0–9.54 wt% leaking into engine oil of SAE 15W – 40 viscosity specifications using Spectro FDM Q600 – Fuel Sniffer. The results are confronted with regard to the determination of the accuracy and precision of the repeatability of measuring diesel fuel in oil with this type of instrument. By expressing the linear dependence between the diesel concentration determined by Fuel Sniffer and the actual diesel concentration in engine oil of model samples, correlation R = 0.998 was obtained. From the point of view of verifying the accuracy of the method, it was not proved that it would be burdened with systematic errors. Precision of measurement by this instrument, expressed as repeatability, reached RSD below 5% only for the concentration of diesel in the oil higher than 3.33 wt%.

“…Chemical substances such Potassium Hydroxide (KOH), Isopropyl Alcohol (IPA) and Potassium Hydrogen Phthalate (KHP) are required to determine TAN in oil samples. Procedures for this test are referred as in [12]. Firstly, 5g oil samples are weighed into a titration vessel and 20 mL IPA solvent are added.…”

This paper described in-laboratory oil regeneration process of aged transformer oil using adsorbent; Fuller’s earth. The niche of this paper is the usage of real aged transformer oil taken from an 11kV/433V in-service power transformer made by ACEC Transformer in 1986. The regeneration process is achieved by forcing a mixture of aged transformer oil and Fuller’s earth through a filter paper with the aid of a vacuum pump, hence producing reclaimed transformer oil. This oil was then inserted in an amber glass bottle, blanketed with nitrogen, tightly sealed, and labelled. To test the effectiveness of Fuller’s earth as adsorbent, parameters of Dissolved Decay Product (DDP) were measured using UV-Visible Spectrophotometer (UV-Vis) by referring to ASTM D6802. In addition, Total Acid Number (TAN) and Breakdown Voltage (BdV) measurement were carried out complying the ASTM D974 and ASTM D1816 respectively. Results of UV-Vis indicated that Fuller’s earth can adsorbed 25.24% of DDP in aged transformer oil. As the DDP decreased, TAN is 84.62% reduced while BdV increased 50%. These findings are parallel with the breakdown voltage mechanism due to acidity emergence. It is proved that Fuller’s earth is effective adsorbent for oil regeneration process.

“…Additional determinations of industrial relevance are the total acid number (128), quality (129), and sulfur content (130) of crude oil, glucose and ethanol in bioethanol (131), butene in ethylene/ propylene/1-butene terpolymers (132) by MIR spectroscopy, saturates, aromatics, resins, and asphaltenes in crude oil by fluorescence spectroscopy (133), nickel and chromium in steel by laser UV spectroscopy (134), and 11 pesticides in agrochemical formulations by a NIR spectroscopy/PLS-based QC with results comparable to HPLC (135). In a typical realtime NIR spectroscopy/PLS application, the natural antimalarial artemisinin was determined in dried leaves of Artemisia annua L. using a hand-held device (136).…”

This report reviews recent literature on the application of multivariate calibration techniques to both first- and second-order data, aimed at the analytical determination of analytes of interest or sample properties in a variety of industrial, pharmaceutical, food, and environmental samples, including examples of process control. The most used data processing tools are briefly described, with emphasis on the advantages that can be obtained by applying specific combinations of multivariate data and algorithms. The main focus is on works devoted to first-order data (i.e., spectra, chromatograms, etc.) combined with partial least-squares regression, which has become the standard for this type of analytical research. A brief discussion on recent work on second-order data and algorithms is also included, as this field is rapidly growing, although at present it does not show, the general applicability of the first-order counterparts.
