Runjie Oil Analysis Lab

The daily volume of oil samples is about 100. The Lab promises to email test reports on the same day when samples are received. With a COA Model 126 Lubricant Analyzer, the Lab can easily test more than 100 samples a day and email out results to customers. Though regular RDE oil analyzers can do about the same volume of samples, the cost of COA Model 126 is about a half of that of the RDE ones. In about a year, the Lab has tested more 19000 oil samples.

Used gear box oil study

A railway lab compared results of used gear box oil between SFE and RDE. The concentrations of iron and copper of SFE were found higher than those of RDE. This is understandable because of SFE’s capacity of catching large wear metal particles. However, the ratio of iron and copper was different, too. With RDE, the ratio is about 3, but with SFE, about 4. The new ratio suggests SFE counts large iron particles into its results but RDE does not.
It was also found SFE’s silicon level was higher than RDE’s. Because trains the lab serves travel through desert, large sand particles are dragged into gear boxes. However, these large sand particles are not detectable by RDE.

Testing grease no longer tough

Testing grease is no longer a tough job. In a COA Model 126 analyzer, grease samples can be sparked directly, and results are reported no more than 3 minutes. With the addition of lithium, a full spectrum of grease, that is, sodium-, calcium-, as well as lithium-based grease lubricant now can be all analyzed by the low cost analyzer.
“Grease test is no longer a “patent” of ICP-OES”, a customer said. Because the investment of a COA analyzer is a lot less than that of an ICP-OES, and because there is no cost of wet chemistry, the owners of Model 126 have a room to cut off price in order to attract consumers.

Painful remote service

Frequent downtime or unreasonable test results are a pain to every customer. Waiting for manufacturer’s remote service is another. Though COA analyzer has full capacities of executing remote services either from internet or email, to date, COA has rarely run any remote services. COA Model 126 is quite stable. Though no small CCD spectrometer is stable enough for metal analysis, theoretically, COA has successful means to offset spectrometer drifts in an invisible way. So, customer can always get expected results in daily quality verification.
