The ability of the Model 3320 and newer Model 3321 Aerodynamic Particle Sizer Spectrometer (APS) to make accurate mass-weighted size distribution measurements of solution metered dose inhalers (MDIs) was evaluated. Measurements of experimental HFA-134a beclomethasone dipropionate MDIs were made with both the APS 3320 and APS 3321 and compared to the Andersen Cascade Impactor (ACI). The mass-weighted size distribution measurements from the ACI and APS 3321 agreed well but were very different… 
Evaluation of Aerodynamic Particle Sizer and Electrical Low-Pressure Impactor for Unimodal and Bimodal Mass-Weighted Size Distributions
The objective of this study was to investigate the feasibility of the Aerodynamic Particle Sizer (APS) and the Electrical Low-Pressure Impactor (ELPI) to study mass weighted particle size

TLDR
Three different methods for the aerodynamic assessment of chloroflurocarbon-fluticasone propionate (Flovent), CFC-sodium cromoglycate (Intal), and hydrofluoroalkane (HFA)-beclomethasone dipropionate delivered by pressurized metered dose inhaler are compared.

TLDR
Results of VM nebulized NaF and albuterol were more consistent and generally equivalent when determined by NGI and ACI and aerosol particle sizes measured by TOF in the APS at both RT and 4 degrees C were larger than results obtained by CI.

Comparison of the TSI Model 3306 Impactor Inlet with the Andersen Cascade Impactor: Solution Metered Dose Inhalers
TLDR
For formulations containing 10–20% w/w ethanol it is shown that an extension fitted to the Model 3306 yielded an improved correlation to those obtained from the ACI, which was found that good correlations between the two instruments were obtained.

TLDR
It has been confirmed that an inlet extension may be necessary for the TSI system in order to give mass results that correlate to the ACI, especially for formulations having significant concentrations of low volatility excipients.

TLDR
TOF aerosol measurement techniques appear to be vulnerable to this type of bias for any suspension formulation in which the drug content is not homogeneously distributed within all particle sizes.

Size analysis of a pressurized metered dose inhaler-delivered solution formulation by an Aerosizer-LD time-of-flight aerosol particle size spectrometer.
TLDR
The present investigation was designed to test the hypothesis that the nonspecific nature of the particle detection system in terms of chemical composition was responsible for the inclusion of smaller non-drug-containing excipient particles in the measured size distribution data from this analyzer.

TLDR
It is shown that significant differences in stage cutpoints exist among Andersen Mark II impactors, which can result in large differences in size distribution measurements made with various Mark IIimpactors.
