This presentation discusses different types of nebulizers used in instrumental analysis. There are two main types of nebulizers: pneumatic nebulizers and ultrasonic nebulizers. Pneumatic nebulizers use a high pressure gas stream to break up liquid samples into a fine mist or aerosol. There are four types of pneumatic nebulizers: concentric tube, cross flow, fritted disk, and Babington. Ultrasonic nebulizers use ultrasonic sound waves to break liquid particles down into a fine mist. The presentation provides details on the working mechanisms of each type of pneumatic nebulizer and ultrasonic nebulizers.

3. Nebulizer:
Nebulizer refers to an apparatus
that converts liquid into a fine mist
and generally use gas flows to
deliver the mist.

4. Types of Nebulizer
There are two types of Nebulizer
1.Pneumatic Nebulizer
2.Ultrasonic Nebulizer

5. Pneumatic Nebulizer
Pneumatic nebulizer sucks the
liquid sample in the flow of high
pressure gas and break into
small drops when strikes the
glass beed.

7. Concentric tube
In this nebulizer 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.

8. Cross flow
The high pressure gas flow across
a capillary tip at the right angle.

9. Fritted disk
The sample solution is pumped
onto a fritted surface through
which carrier gas flows.

10. Babington
Consist of a hollow 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.

11. Ultrasonic nebulizer
An ultrasonic nebulizer is a small
portable device that uses
ultrasonic sound waves to break
liquid particles down into a fog
on that they can inhaled easily.
