ABSTRACT : Measurements : Particle Size Measurements for OINDP Quality – I : Cascade Impactor
Measurements: Particle Size Measurements for OINDP Quality – I: Cascade Impactor Dr. Jolyon P. Mitchell Ph.D., FRSC (UK), C.Chem., C.Sci. Aerosol aerodynamic particle size distribution (APSD) is a critical quality attribute for determining inhaler performance in the quality control environment. This is because likely deposition of inhaled medication in the various regions of the human respirato...
متن کاملDeposition Dosages of Three Cromolyn Forms by Cascade Impactor
Among inhaled asthma therapies, the present study aimed to identify factors for selecting the type of inhalation therapy for asthma. Three methods are used to deliver inhaled cromoglycate, and the airway deposition rate was evaluated using a cascade impactor with 3 dosage forms: dry powder (DP), pressurized metered dose inhaler (pMDI), and solution (jet- and mesh-types). The percentage of parti...
متن کاملMedical nebulizer performance: effects of cascade impactor temperature.
BACKGROUND During operation of a jet nebulizer, the temperature of the nebulizer outlet could decrease by more than 10 degrees C, depending on the nebulizer type and operating conditions, such as driving flow rate and fill volume. The droplet size distribution generated from the nebulizer can be measured by a cascade impactor. However, when the cascade impactor is operated at ambient room tempe...
متن کاملDevelopment of a High Volume Cascade Impactor for Toxicological and Chemical Characterization Studies
This paper presents the design and development of a compact high volume cascade impactor (HVCI). The HVCI operates at a ow rate of 900 l/min and consists of 4 impaction stages equipped with circular slit-shaped acceleration nozzles and a backup lter. The backup lter is placed downstream of the fourth stage and is used to collect the ultra ne particles (dp < 0.1 1m). The major feature of ...
متن کاملParallel particle impactor – novel size-selective particle sampler for accurate fractioning of inhalable particles
Adverse health effects due to exposure to airborne particles are associated with particle deposition within the human respiratory tract. Particle size, shape, chemical composition, and the individual physiological characteristics of each person determine to what depth inhaled particles may penetrate and deposit within the respiratory tract. Various particle inertial classification devices are a...
