Condensation Particle Counters

TSI offers a comprehensive range of Condensation Particle Counters (CPCs) using water, butanol, isopropanol, or diethylene glycol, designed for diverse applications. Our CPCs reliably count airborne particles down to 1 nm in size, with options for high-frequency counting up to 50 Hz. Widely used worldwide in labs, sensitive environments, emissions testing, and air quality monitoring, TSI’s CPCs also pair seamlessly with our nanoparticle sizer (SMPS). With extensive experience in CPC design and application support, TSI is here to help you find the right solution for your measurement needs.

Condensation particle counters are a go-to solution for quantifying ultrafine particles. By condensing a working fluid vapor onto nanoparticles to create optically detectable droplets, CPCs count each particle event and report number concentration with high sensitivity. This method enables research across a range of fields where nanoparticles influence performance, health, or environmental outcomes.

Why CPCs matter:

  • Detect small particles: Sensitivity to particles in the low-nanometer range supports cutting-edge studies in nucleation, combustion, and materials.
  • Real-time data: Capture dynamic events and transient processes with second-by-second updates.
  • Flexible operation: Choose models for mobile surveys, benchtop labs, or high-concentration environments with built-in dilution options.
  • Workflow-ready: USB, Ethernet, and data formats that integrate with lab software and external instruments.

Applications:

  • Environmental and indoor air research focused on ultrafine particle exposure.
  • Engine and combustion studies including cold-start and aftertreatment evaluation.
  • Filtration and media testing to characterize number-based efficiency.
  • Nanomaterial synthesis and process optimization.
  • Instrument method development, including pairing with differential mobility analyzers for size-resolved concentration (SMPS).

Selection guidance:

  • Verify the lower detection size and maximum concentration for your use case.
  • Consider working fluid (e.g., water or alcohol-based) and maintenance preferences.
  • Evaluate sampling flow rates for compatibility with upstream conditioning or classifiers.
  • Plan for remote access and data export to support collaborative analysis.

Built for research settings, CPCs help teams capture reliable number concentration data, accelerate experiments, and compare results across laboratories. The combination of sensitivity, speed, and integration makes CPCs a foundational tool in nanoparticle science.
