Atmospheric sample composition dependence

Each element measured by flame AAS will require from 0.5 to 2 ml of solution depending on the equipment and technique in use. Ambient studies often involve determination of 8—15 elements, and those elements presented at high concentration may be analyzed in a diluted aliquot of the original analyte solution. The number of elements which can be measured in a given sample will be dependent on the composition of the actual atmosphere sampled. 

Combustion oxidation this is the fastest type of oxidation, in which the sample was combusted after a very short exposure depending upon the temperature, atmosphere, specimen composition, thickness and arrangement in the heating container. As a result, sample temperatures became very high during combustion. Therefore the oxidation products were highly deformed and non-uniform in colour, and had very rough surfaces.
