Hey Duarte,

There is a commercial lab that performs ferrographic analysis here in the United States. They're located in Cleveland, Ohio and there web address is www.predictusa.com. Formal name is PREDICT TECHNOLOGIES.

FYI....I've utilized there services for 20 years. Expertise in the art of identification of type of wear particulate is top of the line.

Ferrographic analysis is actually just one piece of the pie. Spectrographic analysis should be performed as well. If the system is a lead/tin alloy system ie. plain bearings, spectrographic analysis will identify lead/tin alloy concentrations in the 3 - 5 um range. Also, this type of system can utilize a patch test which will capture all wear for examination under a bichromatic microscope.

Xi’an TianHou Electronic-Technology Co., Ltd is the leading supplier and manufacturer of oil quality analyzers in China. After established in 1992, THY series oil quality analyzers won praised by insiders in lubrication management.
THY series oil quality analyzers have realized lubricant replacement according to quality. In 2000, THY-20C passed technology achievement appraisal by Lanzhou Military Command. In 2001, it won the second prize for technology progress in the military system of China and national patents which including one invention patent and three design patents. It introduced CIS in the same year. In 2002, the company passed Hi-tech Enterprise Authentication.
Oil quality analyzer detects and measures the dielectric constant of oil. By measuring the complex dielectric constant of oil, it is able to determine the degree of change in the dielectric constant of the oil. Dielectric change is directly related to the degradation and contamination level of the oil and helps the user to optimize intervals between oil changes and to detect increased mechanical wear and loss of the oils lubricating properties.

To guarantee the quality, we have established and perfected quality guaranty system. In 2001, we got ISO9001:2000 certificate. We sticks to firm and standard quality control in production process and carries out modern management. It attaches much attention to employee education and comprehensive enterprise character.

Baloney or hogwash, whichever you like better! Your test results points to nothing. There is absolutely no way to identify with any degree of certainty which parameter caused dielectric change. Is it wear, or ingressed contaminants, or loss of additives, or something entirely different. And BTW, you did not even try to answer the posed question. Shame on you, cheap peddler!
