What are the main components of flame photometer?
A flame photometer has three essential parts. These are: emission system, fuel gases and their regulation, and atomizer. The advantages of flame photometry are the low cost as compared with atomic absorption or atomic emission spectrophotometry.
What is flame photometry and its principle?
The principle of flame photometer is based on the measurement of the emitted light intensity when a metal is introduced into the flame. The wavelength of the colour gives information about the element and the colour of the flame gives information about the amount of the element present in the sample.
What are the requirements for flame photometry?
Flame photometry is good only for elements that are easily excited and do not require very high temperatures (Na, K, Li, Ca are the most widely determined atoms by this technique). between about 1 ng/ml and 1 µg/ml.
What are the different types of flame photometry?
It is divided into three types which are absorption, emission, and luminescence spectroscopy.
Which detector is used in flame photometer?
Flame Photometric Detector or GC-FPD is a technique used to analyse sulphur or phosphorous containing compounds and metals such as tin, boron, arsenic and chromium. An FPD uses a hydrogen/air flame into which the sample is passed.
What are the application of flame photometer?
APPLICATION :- Flame photometry is useful for the determination of alkali and alkaline earth metals. Used in determination of lead in petrol. Used in the study of equilibrium constants involving in ion exchange resins. Used in determination of calcium and magnesium in cement.
What is application of flame photometry?
APPLICATION :- Flame photometry is useful for the determination of alkali and alkaline earth metals. • Used in determination of lead in petrol. • Used in the study of equilibrium constants involving in ion exchange resins.
What is the name of the instrument used in flame emission spectroscopy?
The flame emission spectroscope is a scientific instrument based on flame testing. Data from a spectroscope can be used to: Identify metal ions in a sample.
Which fuel is used in flame photometry?
Explanation: The commonly used fuel gases in flame photometry are acetylene, propane and hydrogen. Oxygen supply is given to the fuel gases. 11.
What are instrumental methods?
The instrumental methods of chemical analysis are divided into categories according to the property of the analyte that is to be measured. Many of the methods can be used for both qualitative and quantitative analysis. The major categories of instrumental methods are the spectral, electroanalytical, and separatory.
What is instrumental method?
Instrumental methods of analysis rely on machines. There are several different types of instrumental analysis. Some are suitable for detecting and identifying elements , while others are better suited to compounds . Compared to simple laboratory tests, instrumental methods of analysis may give improved: speed.
What is the instrumentation of flame emission spectrophotometer?
A flame atomic emission spectrometer is similar in design to the instrumentation for atomic absorption spectrometer. The essential components of an AES are a nebulizer within a spray chamber, a premix burner, flame, monochromator, detector, and readout system.
How many types of instrumental methods are there?
The major categories of instrumental methods are the spectral, electroanalytical, and separatory.
