This document discusses flame photometry, which is an emission spectroscopy technique used to detect alkali and alkaline earth metals. It works by measuring the intensity of light emitted when a metal sample is introduced into a flame. The key components of a flame photometry instrument are the sample delivery system, mirrors, monochromator, slit/filter, detector, and recorder. The sample is atomized in the flame and the emitted light is filtered to the desired wavelength before being converted to an electrical signal that is recorded, allowing for qualitative and quantitative analysis of the metal present.

2. INTRODUCTION:
• It is an emission spectroscopy which is basically used in detection
of alkali metals and alkaline earth metals.
• It is used for both types of analysis, Qualitative as well as
Quantitative
• It is based on movement of intensity of light emitted when a
metal is introduced into flame.

3. INSTRUMENTATION:
COMPONENTS OF FLAME PHOTOMETRY:
• SAMPLE DELIVERY SYSTEM ----- ATOMIZER,
NEBULIZERS, BURNER
• SAMPLE
• MIRRORS
• MONOCHROMATOR
• SLIT / FILTER
• DETECTOR
• RECORDER

4. • SAMPLING DELIVERY SYSTEM:
It is a complete system which delivers the sample into flame.
• SAMPLE:
It presents in the form of liquid which contain unknown metal salts.
•MONOCHROMATOR:
It converts polychromatic light into monochromatic light of a desired
wavelength.
•SLIT / FILTER:
It is basically a part of monochromator and passed a desired single
beam of light.

5. •DETECTOR:
It converts radiations into electrical signals which we can
easily read out through recording system
• RECORDER:
It records the wavelength of the metals.
