What are the characteristics of ideal analytical technique for measuring trace elements in environmental samples?
A.
The choice of analytical method for making trace element measurements of environmental or biological samples depends not only on availability but on a variety of factors: a. multi or single element determination; b. required detection or determination limits; c. required type of sample preparation;
B.
d. possible matrix or interference effects; e. total dissolved solids content; f. liquid or solids analysis; g. required levels of precision and accuracy;
C.
The ideal analytical technique for measuring trace elements in environm e ntal samples must offer: (a) very low detection limits, (b) a wide linear dynamic range, (c) simple interference–free data,
D.
(d) qualitative , semi-quantitative and quantitative analysis, (e) possible simultaneous multielement capability, (f) simple sample preparation, (g) high throughput and low cost per determination.
