OPCs do this by measuring the light scattered by each particle. As a particle passes through the OPC\u2019s sample cell, the particle is illuminated by a high-energy light source: usually a laser beam. Some of the incident light photons may be absorbed or scattered by the particle, and depending on the operating mode of the OPC, the amplitude of absorbed or scattered light is measured. PMS offers a wide variety of OPCs that suit various needs. These include the <em><span style=\"color: #ab2929;\"><a style=\"color: #ab2929;\" href=\"https:\/\/techmaster.com.vn\/en\/pms-lasair-pro-310-airborne-particle-counter\/\">Lasair Pro<\/a><\/span><\/em>, <em><span style=\"color: #ab2929;\"><a style=\"color: #ab2929;\" href=\"https:\/\/techmaster.com.vn\/en\/pms-lasair-iii-110-0-1-micron-particle-counter\/\">Lasair III 110<\/a><\/span><\/em>,\u00a0 <em><span style=\"color: #ab2929;\"><a style=\"color: #ab2929;\" href=\"https:\/\/techmaster.com.vn\/en\/pms-airnet-ii-510-4-particle-sensor-4-channel\/\">Airnet II<\/a><\/span><\/em>, and<em><span style=\"color: #ab2929;\"> <a style=\"color: #ab2929;\" href=\"https:\/\/techmaster.com.vn\/en\/pms-isoair-pro-plus-remote-particle-counter\/\">IsoAir Pro-Plus<\/a><\/span><\/em> to name just a few.<\/p>\n<p>OPCs are commonly used for counting large particles and have a lower size limitation of around 100 nm.

The thermodynamic process that enlarges the particles within the CPC instrument allows the particles to be detected by a traditional OPC sample cell. This allows users to measure particles that are as small as 10 nm (see the <em><span style=\"color: #ab2929;\"><a style=\"color: #ab2929;\" href=\"https:\/\/techmaster.com.vn\/en\/pms-nanoair-10-aerosol-particle-counter\/\">NanoAir\u2122 10 Condensation Particle Counter<\/a><\/span><\/em>).<\/p>\n\t\t<\/div>\n\t\t\t\t\n<style>\n#col-361637030 > .col-inner {\n  padding: 0px 0px 0px 0px;\n}\n<\/style>\n\t<\/div>\n\n\t\n\n\t<div id=\"col-1954556130\" class=\"col medium-7 small-12 large-7\"  >\n\t\t\t\t<div class=\"col-inner\"  >\n\t\t\t\n\t\t\t\n<p>CPCs utilize a working fluid that forms a saturated vapor that can be condensed onto the nanoparticles before they move through an OPC sample cell. The working fluid is brought to a precisely controlled temperature in a chamber inside the instrument to form the necessary supersaturated vapor. As the aerosol particles are sampled and drawn through the chamber with the vaporized working fluid, the particles are brought to the correct temperature and pressure and the nanoparticles are mixed thoroughly with the vapor molecules.<\/p>\n<p>After the vapor and aerosol are mixed, the mixture is cooled. This creates a supersaturated vapor that can now condense on the nanoparticles which act as condensation nuclei, allowing the vapor to form liquid layers of the working fluid on each particle as the vapor condenses.
