Particle analysis is also used to determine particle velocity and surface charging. Particle velocity measurements are important in understanding spray and aerosol processes such as paint spraying, thermal spraying, powder coating, and spray dispensers. Surface charging or zeta potential is used to understand dispersion stability. Zeta potential, an important measurement taken by particle analyzers, indicates the magnitude of the repulsion or attraction between particles.</ins></div></td></tr> <tr><td class="diff-marker" data-marker="−"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #ffe49c; vertical-align: top; white-space: pre-wrap;"><div><del style="font-weight: bold; text-decoration: none;">* Only edit this page if you can improve </del>the <del style="font-weight: bold; text-decoration: none;">content</del>.</div></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div> </div></td></tr> <tr><td class="diff-marker" data-marker="−"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #ffe49c; vertical-align: top; white-space: pre-wrap;"><div><del style="font-weight: bold; text-decoration: none;">* Improper </del>use of <del style="font-weight: bold; text-decoration: none;">this page will lead to permanent banning</del>.</div></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">Particle characteristics analyzers may use blocking or attenuation, or diffraction or scattering techniques. Blockage or attenuation is based on a particle's ability to reduce the transmission of light, radiation (X</ins>-<ins style="font-weight: bold; text-decoration: none;">ray, beta) or electrical field (electrozone). In the light blockage technique, a small volume of the sample is passed between a laser light source and a detector, and the shadows cast by the particles on the detector are measured. Diffraction or scattering is most accurately called low</ins>-<ins style="font-weight: bold; text-decoration: none;">angle light laser scattering (LALLS). Because they are non</ins>-<ins style="font-weight: bold; text-decoration: none;">destructive and non</ins>-<ins style="font-weight: bold; text-decoration: none;">intrusive, LALLS particle characteristics analyzers are the preferred type in many different industries. Some particle characteristics analyzers use ferromagnetic techniques. Others use microscopy and image analysis. Ferrography instruments or ferrographs apply a magnetic field to a dispersion of contamination or ferromagnetic (e.g., steel, cast iron) wear particles in oil, lubricant, grease, fuel, hydraulic fluids and other fluids. A ferrogram is produced with separation of different types of particles, and then analyzed. Microscopy and image analysis techniques rely on capturing an image of the particles and then manual or automatically measuring the particles.</ins></div></td></tr> <tr><td class="diff-marker" data-marker="−"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #ffe49c; vertical-align: top; white-space: pre-wrap;"><div><del style="font-weight: bold; text-decoration: none;">* Please do </del>not <del style="font-weight: bold; text-decoration: none;">edit the sponsored link on the top right corner</del>.</div></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div> </div></td></tr> <tr><td class="diff-marker" data-marker="−"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #ffe49c; vertical-align: top; white-space: pre-wrap;"><div><del style="font-weight: bold; text-decoration: none;">* Please start editing this page after the /noinclude </del></div></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">Particle characteristics analyzers that use image analysis methods allow automation and the capturing of thousands of particles as well as </ins>the <ins style="font-weight: bold; text-decoration: none;">determination of aspect ratio and other shape factors</ins>. <ins style="font-weight: bold; text-decoration: none;">Particle  characteristics analyzers may </ins>use <ins style="font-weight: bold; text-decoration: none;">sedimentation or centrifugal separation, and sieving or filtration techniques.
