Contadores de partículas en aire for the laboratory
Instruments that draw in a known volume of air and count and classify suspended particles by size, normally by means of laser light scattering, in order to characterize the cleanliness of the environment.
contadores de partículas en aire guide
Certification and continuous monitoring of cleanrooms and controlled areas, verification of laminar flows and hoods, and environmental control in pharmaceuticals, medical devices, electronics and hospitals.
How to choose contadores de partículas en aire
- It depends on the particle sizes to be detected
- The sampling flow rate
- Whether a portable unit or fixed/remote monitoring is required
- The target classification of the area and data traceability. Specific values come from the catalog (Sanity)
Frequently asked questions about contadores de partículas en aire
Which counter do I need to classify a cleanroom in accordance with ISO 14644-1?
One with the flow rate and size channels required by the class to be certified (typically 0.3, 0.5 and 5.0 µm) and with current calibration. The standard also defines the number of sampling points according to the area of the room.
Portable, handheld or continuous monitoring?
The portable unit is the workhorse for classification and certification; the handheld one is used for quick diagnostics and locating sources; continuous monitoring with remote sensors is the trend in aseptic filling, where Annex 1 requires permanent surveillance at critical points.
How often is a particle counter calibrated?
The reference practice is annual calibration in accordance with ISO 21501-4, which ensures the accuracy of counting and sizing. Without current calibration, the data are not defensible in an audit.
Can the same instrument be used for microbiological monitoring?
No: the counter measures total particles, not viable ones. Viable monitoring requires microbiological air samplers; the two sets of data complement each other in an environmental monitoring program.
