Here are the frequently asked questions to our company.
Please feel free to contact us for further clarification.
We cannot make an overall determination if it is usable or not. However, if there are criteria for controlling the oil, we can make comparison by determining control items.
Mixture of kerosene and heavy oil can be presumed by analysis of the fuel oil indicator (Coumarin).
Also, by performing sulfuric and Gas Chromatography analysis as well, it enables us to assume contaminated grade.
JIS K2280 reads “diesel fuel oil without Cetane improver indicates the equivalent value as Cetane number. However, Cetane index cannot be abstracted from diesel fuel oil with Cetane improver.” These is relatively an intimate correlation with petroleum-fuel.
Yes. However, JIS specification allows ethyl alcohol within 3%.
Yes. However, in some cases, analysis is not possible because of a duplication of component depending on a type of alcohol.
JPI method is mainly used in Japan, and it reports saturates, Olefin content and aroma contents (mono-, di-, and ply aromatic [TRI+]).
On the other hand, IP method is mainly used in Europe, and it reports only aroma contents (mono-, di-, and ply aromatic [TRI+]).
There is a tendency of having correlation on data to some extent, but we may not be able to make determination sometimes depending on a difference of test material.
We cannot make an overall determination if it is usable or not. However, if there are criteria for controlling the lubricant, we can make comparison by determining control items.
Yes, we can measure weld load, load friction index etc. Please contact us for further details.
We might be able to determine a type of grease by infrared spectroscopy in some cases. Please contact us.
Determination can be performed with 5g of sample at the smallest, but in some cases, correlation cannot be obtained depending on a type of grease, compared with the determination using regular amount of sample. We recommend using the standard amount of sample of 300g for precise determination result.Test Item List of Analytical Testing of Lubricant
Yes. Temperature is set at -20℃ (minus twenty degrees) from a cure of sample to testing. Please contact us for lead time and quotation.
Yes. It is determined by razer diffraction particle size analysis. Please contact us for lead time and quotation.Test Item List for Analytical Testing of Asphalt
TPH (Total Petroleum Hydrocarbon) is analyzed by Gas Chromatography. We can determine an oil type by the pattern of Chromatogram.
Analysis is feasible though accuracy of an analysis could be deteriorated depending on an amount of sample. We propose an appropriate preparation method to customers depending on availability of sample amount. We can provide quantitative analysis of oil with 40mL of sample water.
On standard Gas Chromatography, component of carbon number 6 to 44 is detected. On the other hand, on IR, even component of carbon number over 44 is detected. Therefore, sometimes they do not have a correlation.
In some cases, we might be able to determine by patterns of Chromatogram on Gas Chromatography or patterns of infrared absorption spectrum.
We do not accept a request of gas collection on site. However, we can make an analysis if you send us a sample in Tedlar bag.Test Item List of Analytical Testing of Soil and Water Quality
Yes. You can bring your test vehicle or engine, or we can arrange them. Please contact us which type of vehicle or engine is available for you.
Yes. We can arrange fuel on the market or we can blend special fuel at your request.
Yes. We can disassemble an engine alone. We are authorized for repair and inspection of automobile, so we can overhaul an automobile.
Yes. Our facility is fully equipped with various instruments for measuring size, roughness of surface, weight, etc. Evaluation or photography by our experts are also available.
Yes, of course. In our Chassis Dynamometer, you can set up wide range of temperature or humidity. It is also equipped with instruments of travelling air and insolation, so there are customers who want to use this facility for other purposes.
Temperature: -40℃ through +40℃ (minus forty degrees through plus forty degrees)
Humidity: 30% through 90% (thirty percent through ninety percent)
Yes. You can use Chassis Dynamometer or facility alone as far as you do not take them out of the facility.
It depends on an availability of our facility. Regarding a long-term durability running test of motor vehicle, we can perform it both in our Chassis Dynamometer and on road. Please contact us for details.Test of Motor Vehicle and Chassis Dynamometer
We might be able to accept a testing which is not described on our list. Please feel free to contact us.
No, we do not undertake the analysis of sulfated pitch.
No, we do not undertake the test and analysis of insulation oil with PCB.
