Feb 24, 2014 · Particle Quantification (PQ Index) is the measurement of total ferrous (Iron) particles present in the sample. PQ does not take into account size of particles. The ferrous is …

The dimensionless PQ index, Particle Quantifier Index, is shown in the OELCHECK laboratory report under "Wear" for oil and grease samples. The value informs about magnetisable iron …

Feb 12, 2019 · The PQ Index gives a measurement of the total relative concentration of ferrous material. This test will pick up the presence of larger iron particles, such as a gear tooth or …

Nov 17, 2021 · Find out how wear metals, ferrous debris, contamination elements, wear particle quantification index (PQ / PQI) and additive metals are tested below, what each element on a …

PQ Analysis detects and measures the mass of ferrous wear debris within a lubricant sample irrespective of the size of the wear particles present. The result is reported as a PQ Index.

Apr 25, 2024 · Ferrous Wear Concentration versus PQ Index. Since elemental spectroscopy is generally accepted as having lower accuracy measuring wear particles larger than …

With some instruments there is no quantified result of ferrous content in ppm or mg/ml, instead, a dimensionless index called the “PQ” index is reported. The PQ instrument reports values on a …

May 7, 2018 · A Particle Quantifier Index, or PQ Index, is an important predictive maintenance tool as it measures the total ferrous metal content in lubricants and is an indicator of abnormal …

The PQ index is used to detect all magnetisable wear particles, irrespective of their size, in contrast with AES (atom emission spectroscopy), which cannot detect iron particles > 5 µm. …

Particle quantification, or PQ Index, is the measurement of the total ferrous metal content of an oil. It is often the first method used to determine what other tests, or test programs, should be …
