For oil analysis spectrometers, a large electric potential is set up between a disc and rod electrode with the oil sample in the gap between them. An electric charge stored by a capacitor is discharged across this gap creating a high temperature electric arc which vaporizes a portion of the sample forming a plasma.
Spectrometric Oil Analysis Program (SOAP) is a method used by aircraft operators, including several Air Forces of the World, to test the health of aircraft engines by performing frequent laboratory testing of the engine oil. The tests reveal the chemical composition of any metal particles suspended in the oil samples.
Fourier-transform infrared (FTIR) spectroscopy is a simple technique used in oil analysis. It is specifically used for detecting degradation, dilution, or illegal additives in different types of oils. FTIR spectroscopy uses the interaction of invisible infrared radiation and matter.
A spectrometer is any instrument used to probe a property of light as a function of its portion of the electromagnetic spectrum, typically its wavelength, frequency, or energy. The property being measured is usually intensity of light, but other variables like polarization can also be measured.
The goal of any optical spectrometer is to measure the interaction (absorption, reflection, scattering) of electromagnetic radiation with a sample or the emission (fluorescence, phosphorescence, electroluminescence) of electromagnetic radiation from a sample.
Three sampling procedures commonly associated with engine oil sampling include: sampling a pressurized line before the system filter; using a drop tube in the dipstick tube; and procuring a sample midstream from a drain port while draining the engine.
The acquisition of FTIR spectra is much faster than by conventional dispersive instruments. The FT method produces spectra that show a much better signal-to-noise ratio and, as the wavelength scale is calibrated with a very precise reference laser, provides higher wavelength accuracy than IR.
FTIR spectra reveal the composition of solids, liquids, and gases. The most common use is in the identification of unknown materials and confirmation of production materials (incoming or outgoing). The information content is very specific in most cases, permitting fine discrimination between like materials.
The mass spectrometer, NMR spectrometer and the optical spectrometer are the three most common types of spectrometers found in research labs around the world. A spectrometer measures the wavelength and frequency of light, and allows us to identify and analyse the atoms in a sample we place within it.
Like mentioned previously, spectrometers measure the radiated matter of light, while spectrophotometry measures the color it produces. Spectrophotometers are otherwise known as UV-Vis spectrometers. The output of a spectrophotometer is usually measured in the absorption spectrum of the sample.
Optical spectroscopy (or spectrometry) is the use of an optical spectrometer to study how light interacts with, or is emitted by, a sample. You can use optical spectrometers to measure the transmission, reflection, scattering, or absorption of light on a sample as well as the luminescence from an emitter.
A spectrometer is a device for measuring wavelengths of light over a wide range of the electromagnetic spectrum. It is widely used for spectroscopic analysis of sample materials. The incident light from the light source can be transmitted, absorbed or reflected through the sample.
There are three types of base oils: mineral, vegetable, and synthetic. Mineral oil comes from crude oil and the quality depends on the refining process. Lubes made from vegetable oils are called biolubricants. Synthetic oils are man-made fluids and can be beneficial for use in extreme conditions.
The Four Main Types of Oil

Chemically, petroleum consists principally of hydrogen and carbon, but also contains small percentages of oxygen, nitrogen, sulfur, and traces of metals, such as vanadium, cobalt, and nickel. The common organic compounds include alkanes (paraffins), naphthenes, aromatics, and heterocompounds.

Regarding crude oil, Japan's dependence on Russia accounts for only 3.6 percent, but Japan imports about 90 percent of it from the Middle East, making Russia the largest import destination outside of that region. In that sense, the significance of Sakhalin-1 in terms of Japan's energy security is not small.
Significant reserves of unconventional tight oil such as contained in the Bazhenov Formation are believed to exist in western Siberia. An estimate by Wood Mackenzie of the Bazhenov Formation was that it contained 2 trillion barrels of oil in place; achievable recovery factors are unknown.
Unlike MS spectrometry, NMR spectroscopy is quantitative and does not require extra steps for sample preparation, such as separation or derivatization. Although the sensitivity of NMR spectroscopy has increased enormously and improvements continue to emerge steadily, this remains a weak point for NMR compared with MS.
After more than seven months of full-scale warfare, about 42 million cubic meters of Russian gas still flows through Ukrainian pipelines to Europe each day, sustaining an economic artery for Moscow's sanction-riddled wartime economy while also providing Kyiv a source of revenue worth about $7 billion over five years.
India and China have become the largest buyers of Russian oil as Western nations restrict purchases and impose sanctions. A plan by the major G7 economies - backed by the EU and Australia - to cap the price at which Russian oil is bought has created uncertainty in global markets.
Even in a worst-case scenario, in which there is no piped Russian gas and low demand destruction, BNEF estimates Europe would still have enough gas to endure the coldest winter of the last 30 years without depleting its inventories. Looking further ahead, the region could be well-positioned for winter 2023-24 as well.
But much of that increased output would require further investment and much more time. As a result, a total loss of Russian oil exports would be very damaging for global GDP in the short/medium term. Much higher prices would drive demand destruction (less economic activity) to rebalance the market.
approximately 1 mg/L Parts per million and parts per billion may be converted from one to the other using this relationship: 1 part per million = 1,000 parts per billion. For water, 1 ppm = approximately 1 mg/L (also written as mg/l) of contaminant in water, and 1 ppb = 1 ug/L (also written as ug/l).
The USA could provide us with LNG This week Toby Rice, who runs the country's largest natural gas producer EQT, told the BBC that the US could easily replace Russian supply. "We've got the ability to do more, the desire to do more," he said, estimating that the US has the potential to quadruple its gas output by 2030.
The bloc's proposed gas replacements by the end of 2022 – which include LNG (liquefied natural gas) diversification, renewables, heating efficiency, pipeline diversification, biomethane, solar rooftops and heat pumps – amount to around 102 bcm annually, according to data from the EU Commission's REPowerEU, aggregated ...
