Elemental Spectroscopy/ASTM D5185 Offered by Eurofins TestOil

The presence of wear metals in oil can lead to oil degradation and may indicate the presence of an abnormal wear mode. Early detection through oil analysis can head off these issues. To that end, Eurofins TestOil offers tests for larger particles (>7 microns) and a test for smaller particles, elemental spectroscopy.  

The Elemental Spectroscopy test by ICP (inductively coupled plasma), ASTM method D5185, uses a spectrometer to measure the levels of specific chemical elements present in the sample.

During the test, energy is applied to the prepared sample via a plasma flame. This raises the energy level of the individual atoms.  When the atoms then lose energy, they release light at specific wavelengths. Individual light frequencies in the spectrum are measured and quantified to determine the presence and quantity of specific elements.

Monitoring the concentration of metallic elements, such as iron, copper, tin, aluminum, nickel, chromium, titanium, vanadium, silver, and lead can provide important information regarding machine condition. Wear rates can be trended and abnormal wear modes can be detected.

Many contaminants have metallic components; such as silicon, boron, sodium and potassium, which can also be monitored. Increases in contaminant metals can indicate ingression of dirt, coolant or process contaminants. Some additives also have metallic components that can be monitored with elemental spectroscopy.

Eurofins TestOil Analyst/Field Technician Matt McMahon explains, “Sources of particles present in the lubricant can originate from abnormal wear and corrosion. An example of abnormal wear from a plain bearing would be soft metals such as lead, tin, antimony, and copper.”  

Elemental spectroscopy is a standard test that is included in the Eurofins TestOil basic test package. Information provided by this test includes:  

1.  Type of additive package based on the presence of elements such as calcium, magnesium, phosphorus, zinc, barium and molybdenum. 

2.  The quantity of individual contaminant elements such as silicon, boron, potassium, lithium and sodium.

3.  The amount of wear metals present in the current sample which can be trended with historical results.  

This test can be performed on automotive and industrial lubricants including water- based fire-resistant hydraulic fluids.

While elemental spectroscopy has a particle detection limit of 7 microns, Eurofins TestOil offers a number of tests for larger particles including: ferrous wear concentration, and particle count.
