Nebulisation techniques:
The accuracy, precision and detection limits of flame AAS depend on how the analyte sample is introduced into the atomiser. We need to transfer a reproducible and representative portion of a sample into an atomiser which depends on the physical and chemical state of the analyte and the sample matrix. The sample introduction is achieved with the help of a nebuliser. The generally used nebulisation techniques are ultrasonic nebulisation, pneumatic nebulisation, electrothermal vaporisation and hydride generation.
Atomic absorption spectrophotometry (AAS) is now a routinely and widely employed technique for trace and ultratrace analysis of complex matrices of geological, biological, glass, environmental, industrial, cement, marine sediment, pharmaceutical, engine oil or any other kind of samples. An atomic absorption techniques using flame are rapid and precise and are applicable to about 67 elements. The electrothermal methods of analysis instaed are slower and less precise; thus, these are more sensitive and require much smaller samples
AS THIS ALKALI METALS HAS LARGE SIZE AND LESS IONISATION ENERGY THEY LOSE THEIR OUTERMOST ELECTRON EASILY. PHOTOELECTRIC EFFECT MEANS EJECTION OF ELECTRONS FROM A METAL WHEN THEY

Q. Illustrate crystal field splitting in octahedral complexes? Initially in a free ion state (I) all the orbitals are in degenerate state. In state (11), all the five orbitals
why beryllium show simmillarity with Alumminium
how to calculate equivalent weight of phenol
Since fluorine is very electronegative as a result hydrogen develop a very positive character. As a result the H-bonding is very tough because of large difference in electronega
