Flame photometer is an analytical instrument used in clinical laboratories for determining of sodium, potassium, lithium and calcium ions in body fluids. A flame photometer has three essential parts. These are: emission system, fuel gases and their regulation, and atomizer.
What are the components of flame photometer?
Components of a Flame Photometer
- Flame.
- Nebulizer.
- Mixing Chamber.
- Colour Filters.
- Photo Detector.
What are the requirements for flame photometry?
A simple flame photometer consists of the following basic components: Source of flame: A Burner in the flame photometer is the source of flame. It can be maintained in at a constant temperature. The temperature of the flame is one of the critical factors in flame photometry.
Which lamp is used in flame photometry?
Flame photometry employs a variety of fuels mainly air, oxygen or nitrous oxide (N2O) as oxidant. The temperature of the flame depends on fuel-oxidant ratio….
| Name of the element | Emitted wavelength range (nm) | Observed colour of the flame |
|---|---|---|
| Calcium (Ca) | 622 | Orange |
| Sodium (Na) | 589 | Yellow |
| Barium (Ba) | 554 | Lime green |
What is flame photometry instrumentation Slideshare?
INTRODUCTION: • Flame photometry (more accurately called Flame Atomic Emission Spectrometry)is a branch of spectroscopy in which the species examined in the spectrometer are in the form of atoms • A photoelectric flame photometer is an instrument used in inorganic chemical analysis to determine the concentration of …
Which type of burner is used to operate AAS?
The oldest and most commonly used atomizers in AAS are flames, principally the air-acetylene flame with a temperature of about 2300 °C and the nitrous oxide system (N2O)-acetylene flame with a temperature of about 2700 °C.
What are the two parts of flame photometry?
There are four basic components to a Flame Photometer – a flame, nebulizer and mixing chamber, colour filters, and a photo detector.
What type of flame is used to perform flame test?
A non-luminous flame is employed to perform the test. It is obtained by keeping the holes the burner open.
Which type of burner sample is directly introduce in to flame?
The burner is called total consumption because the entire aspirated sample enters the flame or in other words the sample solution is directly aspirated into the flame. All desolvation, atomization, and excitation occurs in the flame.
What is the function of nebulizer used in flame photometer?
Flame Photometer Components: The Nebulizer breaks up the sample into atoms. The mixing chamber mixes the relevant solution with the sample. The colour filters show us which metals are present.
What is the working principle of flame photometry?
Flame Photometry works by measuring the intensity of light emitted (measured using a wavelength of a colour) when the element is exposed to a Flame.
How many types of burner are found in flame photometry?
There are various types of burners used in Flame Photometry such as Mecke burner, Laminar flow burner and total consumption burner. Fuel and oxidant are essential for production of flame.
What are the applications of flame photometer?
Flame photometer can be applied both for quantitative and qualitative analysis of elements. The radiations emitted by the flame photometer are characteristic to particular metal. Hence with the help of Flame photometer we can detect the presence of any specific element in the given sample.
How much does a single channel flame photometer cost?

What is the use of nebuliser in flame photometry?
Source of flame: A Burner in the flame photometer is the source of flame. It can be maintained in at a constant temperature. The temperature of the flame is one of the critical factors in flame photometry. Nebuliser: Nebuliser is used to send homogeneous solution into the flame at a balanced rate.
How to calibrate the photometer and galvanometer?
The flame of the photometer is calibrated by adjusting the air and gas. Then the flame is allowed to stabilize for about 5 min. Now the instrument is switched on and the lids of the filter chamber are opened to insert appropriate colour filters. The readings of the galvanometer are adjusted to zero by spraying distilled water into the flame.
