Development 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 کاملCalibration Studies of the Drum Impactor*
A b s t r a e t ~ l i b r a t i o n studies were performed on the Davis Rotating-drum Universal-size-cut Monitoring (DRUM) sampler utilizing fluorescent monodisperse aerosols of polystyrene latex. The DRUM sampler is an eight-stage Lundgren-type rotating drum cascade impactor utilizing a series of single round jets for each stage including low-pressure stages. The DRUM sampler operates continuo...
متن کاملa study on the design of bio-ethanol process from date wastes of sistan and baluchistan province
اتانول کاربردهای متنوعی در صنایع لاستیک سازی، رنگسازی، حلالها ومکمل سوخت خودرو دارد. اتانول برخلاف نفت از جمله مواد تجدیدپذیر محسوب می شود که مشکلات زیست محیطی و آلودگی نیز ایجاد نمی کند. استفاده از اتانول به عنوان مکمل سوختخودروها از جمله مهمترین مصارف صنعتی این ماده بشمار می رود. با توجه به این موضوع تحقیق و توسعه در زمینه تولید اتانول با درجه خلوص بالا در سطح جهان، و نه تنها در کشور های پیشر...
Deposition 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...
