Cleanroom Condensation Particle Counter

Certain life science applications benefit from detecting particles smaller than traditional cleanroom size channels. TSI cleanroom condensation particle counters (CPCs) expand visibility into the submicrometer range, helping teams examine aerosol behavior during investigations, airflow assessments, and system characterization.

CPCs are well suited for:

• Evaluating filtration performance and potential leakage pathways during maintenance or qualification.
• Studying airflow patterns around critical points, transfer ports, and isolator gloves.
• Characterizing background aerosol conditions during equipment start-up or process changes.
• Supporting research and development when advanced sensitivity is required.

By condensing vapor onto very small particles, CPCs enable counting of ultrafine aerosols that standard optical counters may not detect. This additional layer of information helps quality and engineering teams understand complex events and refine environmental controls. CPC findings can be paired with nonviable particle data from optical counters and microbiological results from active air samplers to build a complete picture of environmental conditions.

TSI designs CPCs with cleanroom compatibility and practical operation in mind. Intuitive workflows and data export support integration with existing documentation practices. Whether you are validating an isolator modification, optimizing airflow in a Grade A zone, or exploring aerosol generation during new operations, CPCs offer high-sensitivity measurement that complements routine monitoring in life sciences facilities.
