Applying the minimum sample volumeįormula above, gives Vs as 5.68 liters for each individual sample.
#BECKMAN COULTER PARTICLE COUNTER ISO#
The sample volume of air required to be sampled to ensure that 20 actual particles would likely beĭetected if the particle concentration was at the class limit for 0.5 μm.įrom the ISO 14644-1 table, the Class 5 limit for 0.5 μm is 3520. Vs is the minimum single sample volume per location, expressed in litersĬn,m is the class limit (number of particles per cubic meter) for the largest considered particle sizeĢ0 is the defined number of particles that could be counted if the particle concentration were at theįor illustration, to classify a cleanroom, for example to ISO Class 5 at 0.5 μm, we would need to consider The minimum sample volume, Vs, for each sampling location can be determined by using the following equation. However it should be noted that for classification, ISO 14644-1 does specify minimum sample volumes.

However it is not necessary to actually sample a full cubic meter for routine monitoring and troubleshooting, even in the case of annual or bi-annual re-classification of the cleanroom. The ISO 14644-1 limits are expressed in particles/m3 of air. The table below, reproduced from ISO 14644-1, shows how airborne particulate cleanliness is described as the number of particles, of size greater than a specific value, in a fixed volume of air expressed as a concentration. ISO 14644-1, Cleanrooms and associated controlled environments-Part 1: Classification of air cleanliness, is a standard for designating the classification of airborne particulate cleanliness within a cleanroom or clean zone. Troubleshooting filtered process environments on an as needed basis.Annual or Bi-Annual certification of clean rooms or controlled environments to ISO 14644-1.There are three primary applications categories for air particle counters which include handheld models. What are Handheld Particle Counters used for? Examples - Food and beverage, dairy packaging, hospital pharmacies. Precision, contamination sensitive industrial segments such as Optics, Aerospace, MEMS, Print-heads etc.

MET ONE pioneered the concept of packaging an optical particle counter into a handheld instrument almost 20 years ago and since that time the technologies now available in our increasingly connected, mobile world have enabled enormous opportunity where saving time and money is of real customer value.
