Which device is used to aerosolize the sample before introduction to the flame?

• A. Beaker
• B. Nebulizer
• C. Light
• D. Monochromator

Answer: (B)

Creating an aerosol is the essential step here: the liquid sample must be turned into a fine mist so it can be carried into the flame where it is atomized for measurement. The device that does this is a nebulizer. It uses a carrier gas to shear the liquid into droplets and feeds them into the spray chamber and then into the flame, giving a consistent droplet size and efficient transport—key for stable, accurate readings in flame-based analysis. A beaker merely holds liquids, not convert them to an aerosol. Light is related to detection or illumination, not aerosolization, and a monochromator selects specific wavelengths after the sample is in the flame, not the method of introducing the sample.
