Compound2 has a boiling pointof 89-C, which of the compo s a boiling point oont of soc compound Y has a bolling point of 110 C, and which of the compound will have the shortest retention time 2.) The area of a peak from proportional to the percentage of that component in equal to 100%. If a gas chromatograph using a thermal conductivity detector is the sample so the sum of the peak areas is we the area of a triangle may be used to calculate the peak area. assume that the peaks can be approximated as triangles, the equation for A base x height se triangulation to calculate the area for peak A and peak B. Make sure figures when measuring with your ruler. to use proper significant a.) Identify peak A and 8 as either toluene (B.P. 110.6°C) or cyclohexane (B.P. -80.7 b.) Calculate the area for each peak. c) Calculate the % of A and 96 of B. (Show work) d.) Which compound has the longer retention time?_ Air peak Injection

Solution

a) The peak A is of toluene (B.P is 110.6°c) and the peak B is of cyclohexane with B.P 80.7°c .

b) the area of the peak and percentage can be calculated if the measurements are given but here as the photo is digital its hight and width may change from one device to another unlike paper where the hight and width will be constant.. So the area of the peak(b) and percentage of each individual compunds (i.e sub question b and c respectively) cannot be calculated.

d) Actually the retention time is the time spends by a compound in the column after it is injected into the column. The compound with low Boiling point evaporate easily and therefore its retention time will be less as compared to those of high Boiling Point. Here in this case toluene has high retention time as compared tp cyclohexane.
