Analysis for oil

You have probably heard of different kinds of analysis for oil, but you may not be fully informed. This article will help you learn about the different types of tests that are used to analyze oils, including FTIR, DL test, and JAPEX Research Center. These tests help you determine the properties of the oil, including its density, viscosity, and particle count.


Getting an accurate viscosity analysis is critical for maintaining your equipment and maximizing its performance. In addition to determining proper oil change intervals, it can help you detect and prevent contaminants and recommend a course of action to keep your machine running smoothly.

It is important to understand that changes in viscosity can be caused by a variety of factors. Among the most common causes are the presence of oxidation, water, and solvents. Typically, viscosity changes of 10 percent or more are considered a “critical” viscosity change.

When performing an oil viscosity analysis, a sample is collected from the container, then transferred to a vacuum suction pump. Then, a Colorimeter is used to measure the viscosity of the test sample.

Particle count

Particle count is a common test used for industrial oil analysis. The results can help determine whether the fluid is dirty or clean. This data can also tell you whether it is time to replace the fluid. It is often a good idea to perform the test on a regular basis.

There are several different tests that are commonly used to detect particles in an oil sample. The Light Blockage Method is one of the most popular. Using a laser focused on a capillary, it counts the amount of light blocked by particles.

The flow decay method is another example. In this test, a sample of oil is passed through a screen that has been calibrated to measure the amount of fluid passing through. A software algorithm then translates the data into a particle count.


If you’re curious about how a new batch of oil looks, you might want to try FTIR analysis. While this technology isn’t as comprehensive as an electron microscope or x-ray spectroscopy, it does offer a more granular look into the molecular structure of the substance. Basically, the FTIR method uses an infrared spectrometer to take a close look at the material. This can be done without altering the substance, making it ideal for testing a wide variety of oils. The result is a more accurate assessment of the product’s quality.

Using FTIR to its fullest extend will reveal a number of useful facts and figures. For example, you can tell which samples are fresh and which aren’t. Additionally, you can tell which ones have been degraded or diluted. You can also determine whether or not the sample has undergone some abrasion or chemical treatment, which can help you determine its long-term viability.

DL test

Oil analysis is a process that involves analyzing oil samples to determine the presence of contaminants. The tests can detect various forms of contamination and provide valuable information about the health of the engine and the components. This information can help fleet operators plan and perform maintenance.

Some key indicators of contamination include the acid number and the viscosity of the oil. In addition, high levels of wear metals can indicate an abnormal condition or an imminent failure.

There are several tests that can be performed by an oil analysis lab. Particle counting, viscosity, acid number and base number are just some of the options.

Optimal control of oil analysis equipment

Oil analysis is a key component in your fleet’s maintenance schedule. It can be used to reveal the current condition of your engine and recommend actions to prevent damage. However, the process is not always straightforward.

The first step is to determine which oil testing methodology will suit your needs. For example, you may want to consider particle counting, elemental analysis, or FTIR spectroscopy. All of these tests can be useful in determining the condition of your engine. If your equipment requires synthetic oil, you might want to consider that as well.

Using a colorimeter to measure the viscosity of an oil sample can provide useful information. This measurement can help you understand how thick your oil is, and how likely it is to break down. In addition, the change in viscosity can indicate oxidation.

JAPEX Research Center

The Japan Petroleum Exploration Co., Ltd. (JAPEX) has been contributing to a stable energy supply in Japan for more than 50 years. It is aiming to become a comprehensive energy company by developing new technologies and renewable energies. Besides producing oil and natural gas, JAPEX also participates in overseas oil and gas development.

A key focus for JAPEX is on the development of new technologies that could contribute to a carbon-neutral society. This includes the demonstration tests of CO2capture technologies and the development of environmentally friendly businesses. For instance, Japex plans to diversify its gas sources to meet the increasing demand for gas in Japan. And it has started producing shale oil at its Onnagawa tight formation in Akita prefecture.
