As each particle passes through a precision-etched nanoconstriction in a microfluidic cartridge, it displaces electrolyte and generates a measurable resistance pulse. The amplitude of the pulse determines the particle diameter, providing real-time size and absolute concentration measurements for particles in the 50 nm to 10 micron range.”","path":"/entities/spectradyne-united-states-q64142609#company-fact-content-native-digital-agencies-0315656ec124eae2-a-b68ce81913d97cabc87c","questionPaths":["/entities/spectradyne-united-states-q64142609#company-answer-content-native-digital-agencies-0315656ec124eae2-a-b68ce81913d97cabc87c"]},{"id":"content-native-digital-agencies-0315656ec124eae2-a-25467032be7940d2c18c","label":"What is the difference between the ARC and nCS2?","value":"“Both instruments use MRPS to measure nanoparticle size and absolute concentration.
