Homework Answers
Kovat’s Retention Index is the logarithmic scale that relates the retention time tmr of an analyte to those of linear alkanes in a column containing the stationary phase. According to homologous series method (eg. linear alkanes) elutes in the increasing order of their molecular masses, for instance lowest molecular weight, melting point, boiling point compound elutes first due to the intermolecular forces in the organic compound.
The expression relating number of carbons of the analyte and its retention time is related as:-
where n is the smaller analogue carbon series while N larger homologue carbon series.

Exercise 3: Determining the time-out in CPG The best-known method of estimating the dead time tM consists in measuring the retention time of an unretained compound (commonly methane in GC). Another method is proposed here using the relation used in establishing retention indices, namely that in a homologous series of organic compounds one can write, if the temperature of the column does not vary: log (tr-t = an + b t represents the retention time of the compound with n...

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...
