Question
generally speaking, which of the following has the lowest (besr) detection limits the widest linear range, the fatest sample throughput or the lowest purchasing price a) FAA b) GFAA c) ICP-OES d) ICP-MS generally speaking, which of the following has the lowest (besr) detection limits the widest linear range, the fatest sample throughput or the lowest purchasing price a) FAA b) GFAA c) ICP-OES d) ICP-MS generally speaking, which of the following has the lowest (besr) detection limits the widest linear range, the fatest sample throughput or the lowest purchasing price a) FAA b) GFAA c) ICP-OES d) ICP-MSExplanation / Answer
From the given list, the following can be classififed on the basis of,
The lowest (best) detection limits the widest linear range : d) ICP-MS and b) GFAA : these two have the best detection limits. b) GFAA which is Graphite furnace AA has 100-1000 times better sensitivity then simple AA.
Tthe fatest sample throughput : a) ICP-MS and c) ICP-OES. They can be used for analysis of more then 40 samples per minture with great precision.
The lowest purchasing price : a) FAA followed by b) GFAA : These are the lowest cost instruments for analysis when compared to ICP-OES and ICP-MS the most expensive of all.
