What I entered was wrong and are the 5 options I just have them
in the wrong order. Thanks for your help.
Homework Answers
Ans - The correct order is-
-Goal of analysis
-sample preparation (process of transforming a sample in to a form that is suitable for analysis)
-choosing of detector (choosing a detector that is specific for a particular element or class of compound)
- slecting of coloumn (choices are the stationary phases, diameter,length,and thickness of stationary phase is most useful.)
- choosing ths injection method ( how to inject the sample by the mean of split injection , splitless injection or On-coloumn injection )

GC Experimental Data Analysis I) One method for quantitative determination of the concentration of constituents in a sample analyzed by gas chromatography is the area normalization method. In this method, complete elution of all of the sample constituents is necessary. The area of each peak is then measured and corrected for differences in detector response to the different eluates. This correction is accomplished by dividing the area by an empirically determined correction factor. The concentration of the analyte is found...
