- 1. Course Name: Instrumentalmethod of analysis-iii Course code: ACCE 3203 Topic: Types of Nebulizer 1 By ASIF PAPPU
- 2. Presentation on: Types ofNebulizer • Topics • Definition • Types of nebulizer • Pneumatic nebulizer • Concentric tube • Cross flow • Fitted disk • Babington • Ultrasonic nebulizer 2
- 3. Nebulizer: Nebulizer refers toan apparatus that converts liquid into a fine mist and generally use gas flows to deliver the mist. 3
- 4. Types of Nebulizer Thereare two types of Nebulizer 1.Pneumatic Nebulizer 2.Ultrasonic Nebulizer 4
- 5. Pneumatic Nebulizer Pneumatic nebulizersucks the liquid sample in the flow of high pressure gas and break into small drops when strikes the glass beed. 5
- 6. Types of PneumaticNebulizer There are four types of pneumatic Nebulizer 1.Concentric tube 2.Cross disk 3.Fritted disk 4.Babington 6
- 7. Concentric tube In thisnebulizer the liquid sample is drown through a capillary tube by a high pressure stream of gas flowing around the tip of tube. The high velocity gas break up the liquid in droplets and carried to atomizer. 7
- 8. Cross flow The highpressure gas flow across a capillary tip at the right angle. 8
- 9. Fritted disk The samplesolution is pumped onto a fritted surface through which carrier gas flows. 9
- 10. Babington Consist of ahollow sphere in which a high pressure gas is pumped through a small orifice in the spheres surface. The expanding jet of gas nebulizes the liquid sample flowing in a thin film over the spheres surface. 10
- 11. Ultrasonic nebulizer An ultrasonicnebulizer is a small portable device that uses ultrasonic sound waves to break liquid particles down into a fog on that they can inhaled easily. 11
