The Option PA package has been developed to facilitate the use of the MCA-8000D for particle counting in airborne (Size Calibration) and liquid suspended1 (Number Calibration) particle applications. The unit is calibrated and certified traceable to the National Institute of Standards and Technology (NIST). The Option PA package is capable of detecting pulses from 5 mV to 10 V. The MCA-8000D is typically connected to the output of a particle sensor. It detects and displays a spectrum of pulse heights allowing the user to determine if a given particle size is producing the correct voltage. The software included with the MCA provides information on the peak center (centroid and mean calculation) making it easy to determine if the peak is in the correct position. The MCA is internally calibrated to convert the MCA channel scale to a mV scale and therefore loads automatically, making it unnecessary to load calibration files manually.
