What are the applications of flame emission spectroscopy?
Table of Contents
APPLICATION :- To estimate sodium, potassium, calcium, lithium etc. level in sample of serum, urine, CSF and other body fluids. Flame photometry is useful for the determination of alkali and alkaline earth metals. Used in determination of lead in petrol.
Which of the following is application of flame photometry?
Explanation: The applications of Flame emission photometers are analysis of biological fluids, determination of sodium and potassium in soil and determination of metals such as Mn and Cu. It is also used for the analysis of plant materials and industrial cements.
What is the purpose of flame in flame photometry?
A photoelectric flame photometer is a device used in inorganic chemical analysis to determine the concentration of certain metal ions, among them sodium, potassium, lithium, and calcium. Group 1 and Group 2 metals are quite sensitive to Flame Photometry due to their low excitation energies.
Which source is used in flame photometer?
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.
What are the applications of atomic absorption spectroscopy?
Atomic absorption spectroscopy is utilized across many industries and is instrumental in the detection of metals within a sample. As such, this process is commonly utilized in pharmacology, archaeology, manufacturing, mining, and forensics.
What are the roles of the flame and plasma in electron emission spectroscopy?
Atomic Emission Spectroscopy The analyte solution is introduced into a flame, discharge, or plasma to vaporize it. The high temperature atomization of the analyte drives the atoms to high energy levels. As they return to ground states, they emit photons of characteristic wavelengths.
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. The photo detector tells us which metal the sample contains and to what concentration level.
Which region of the flame is most useful for flame AAS?
Chromium is typically determined by flame AAS using an air-acetylene flame or a nitrous oxide-acetylene flame. Although chromium has a large number of resonance lines of similar sensitivity, the 357.9 nm line is most commonly used.
Which of the following is an application of Atomic Absorption Spectroscopy?
Which of the following is not an application of flame emission spectra photometer?
10. Which of the following is not a detector used in Flame emission photometers? Explanation: Detectors used in Flame emission photometers are Photovoltaic cell and photo emissive tubes. Photovoltaic cell is also known as photronic cell.
Why are alkali metals used in flame photometry?
The basis of flame photometric working is that, the species of alkali metals (Group 1) and alkaline earth metals (Group II) metals are dissociated due to the thermal energy provided by the flame source. Due to this thermal excitation, some of the atoms are excited to a higher energy level where they are not stable.
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.
What is flame emission spectrometry used for in chemistry?
Nevertheless, flame emission spectrometry is widely used for the determination of the alkali elements (lithium, sodium, and potassium), whose excitation states are low enough to be populated at flame temperatures. Higher-energy sources produce higher temperatures and therefore more emission lines.
What is the importance of spectrophotometer in biochemistry?
The spectrophotometer is essential in quantitative analysis of biochemistry practical such as in determining the unknown concentration of a given species through absorption spectrometry. A perfect example is the nucleic acid in a protein. Enzyme assay is the primary use of spectrophotometry.
How can flame photometry be used to analyse soft drinks?
Soft drinks, fruit juices and alcoholic beverages can also be analysed by using flame photometry to determine the concentrations of various metals and elements. The method of analysis is very simple and economical.
