What is particle counting?
Particle counting is used to determine the quality of a sample. Cleanliness and suitability of a sample for its intended application can be determined through particle counting finding size, number and distribution of particles. Using particle counting machines ( http://mindex-ltd.co.uk/manufacturers/stanhope-seta/ ) to count and monitor particles saves both time and money, and can also allow for the most accurate results.
What is particle counting used for?
Particle counting using machines such as those available from Stanhope Seta is commonly used to assess fuel cleanliness, where the problems caused by particles are blockage, wear and erosion in fuel systems.
Laser particle counting
Laser particle counting uses the light emitted by a laser to illuminate cells through which samples are passed. Particles in the sample then cast shadows onto the sensor behind the cell. Laser counting like this is typically used for measuring particles in liquid and the advantages are as follows:
- Programmable via PC
- Quick test time
- Option for cumulative or distributive results
- Particles/volume or cleanliness codes
- Simple operation
- Stand-alone or PC controlled versions
Applications – Which instruments you should use for your samples
(Just some examples)
Petroleum fuels and oils – Particle analysis of fuel provides data on filter efficiency and system cleanliness. Also it is a large indicator of cross contamination or oxidation of fuels in distribution and storage systems. Instruments which should be used include the AvCount2 and the AvCountLite.
Lubricants – Particle counters are used for oil contamination analysis in hydraulic and lubricating oil systems, this is incredibly important. The machines that can be used for this are the AvCount2, the AvCountLite and the AvCount Lube.
Power generation – Particle counting is now a standard method when it comes to monitoring transformer and insulating oils for metallic particles and product of oxidations, with machinescommonly used again including the AvCount2, the AvCountLite and the AvCount Lube.
Filter manufacturers – The cleanliness and sanitation of components in some industries including but not limited to aerospace and optical electronic is monitored by measuring the particle count of flushing fluid during and after processing using either AvCount2 or AvCountLite.
This is only an introduction to particle counting too, if you would like more information or have any questions which you would like answering, we highly recommend that your research online or contact a supplier and marketer such as Mindex whom would be more than delighted to assist you.
