#(i)# #"AAS is sensitive......."# And in fact AAS is good at #"ppm"# levels, that's #"parts per million"#, i.e. #mg*L^-1#.

#(ii)# #"AAS is atom specific......."# Given appropriate sample preparation, AAS may be made PARTICULAR to a particular element.

#(iii)# #"AAS is fairly routine......."# There are vast data on sample preparation and measurement. Given a required analysis it is fairly easy to develop an experimental protocol - and these are developed in house by the operator (as of course they should be).

As with any analysis, it should be noted that the first assignment is typically to create a calibration curve. To do this, we analyze the response of known analyte concentrations, create a calibration curve that is linear to a first approximation, and match the unknown sample to the curve.

undefined 1. Sensitivity: Atomic absorption spectroscopy offers high sensitivity, allowing for the detection of trace amounts of elements in a sample.

2. Selectivity: The technique is highly selective, enabling the precise identification and quantification of specific elements in complex mixtures.

3. Wide Elemental Range: Atomic absorption spectroscopy can analyze a broad range of elements, providing versatility in applications across various scientific disciplines.
