SelftestProblems
1) GC-columns Answer 2) Which peak corresponds to 1,2,4-TCB? Answer 3) Peak area 100 times larger Answer 4) Unlabeled GC columns Help Answer 5) Which animation is correct? Answer 6) Concept map Hint
End of chapter6) Concept map
Problem:
Draw a concept map that shows how you would develop a suitable procedure for analysing...
6a) ...a solvent extract from an environmental sample.
6b) ...a solid sorbent that contains the extract from an environmental sample.
Assume that there are impurities in the sample that have to be separated from the target compound. Don't bother about the quantification. This will be the focus of the next chapter.
Help:
You have to decide between HPLC and GC, you have to decide for a suitable detector and you should find chromatographic conditions that allow for a fast separation.
