The Leaders in Metrology Quality You Can Stand By

Particle Counter Calibration Services in Los Angeles

Serving Customers Nationwide Quickly and Efficiently

Recently installed, operationally qualified, performance validated, and fully commissioned (June 22, 2018), Micro Quality Calibration (MQC) now has the added metrology service capability for the calibration and maintenance of airborne particle counters and particle counting devices.

MQC realizes that particle counters and particle counting instruments are essential tools for measuring airborne contaminant particles in controlled environments, such as cleanrooms, that are in use across many applications and industrial sectors where accuracy is vital. These include but are not limited to cleanroom validation agencies, hospitals, semiconductor companies, and pharmaceutical manufacturers.

The MQC Particle Counter Calibration System/Bench uses an optical particle detection “Moody Method” using a classifier and a Condensation Particle Counter (CPC). To carry out this method of calibration, the laboratory has a calibration procedure, internal laboratory document covered by its A2LA accreditation, specifying all the steps that should be followed to calibrate particle counters in air or condensed particle air. This type of calibration begins with the Certified Reference Material (CRM) standard size microsphere particle suspensions and a CPC certified by an accredited laboratory.

MQC possesses the capability to perform accredited calibrations according to the following parameters:

Amount of Substance – Particulate Calibration



Expanded Uncertainty of Measurement (+/-)


Particle Counting Efficiency

(0.01 to 1) μm

(0 to 100)% of count

2.4% of reading

Condensation Particle Counter and Microsphere CRMs

Particle Sizing

(0.3 to 5) μm

1.1% of reading

Microsphere CRMs

All particle counters and particle counting instruments calibrated and certified by MQC comply with all the provisions and requirements of ISO/IEC 17025 : 2017, ANSI/NCSL Z540-1 (R2002) superseded in 2008 by ANSI/NCSL Z540.3 : 2006 (R2013), ISO 14644 1/2 : 2015, ISO 21501-4 : 2007, FS209E, USP 1116 and USP 797.
