1 A GC sample of a mixture of two compound produces a single peak in the chromatograph. Give two factors that you could change in the GC experiment to increase the resolution so that the two compounds are seperated.

Solution: Factors

-The optimising GC over temperature ramp, using a lower temperature rate before the time the overlapping happens.

-Another factor for this problem is reduction in ramping time.

-Optimize the carrier gas velocity (according to Van d method). Probably it is necessary to change the linear velocity of carrier gas. Try to reduce the velocity.

A student separated two unknown compounds using Fractional Distillation followed by Gas Chromatography. The GC column had a non-polar liquid stationary phase and Helium was the mobile phase. Using the following data, determine the identity, boiling point and percent composition for each of the compounds in the GC sample. Explain reasoning. Your left peak has a percent composition of 20.49% and the right has 79.6%. Hexane boiling pint is 69.2 Heptane boiling boing is 98.5 Methanol is 65.1 Octane 126...

Suppose you are trying to separate a mixture of compounds using reversed-phase liquid chromatography (RPLC). On the first run, using a mobile phase containing 40% tetrahydrofuran and 60% water, the peaks all elute between 0 and 3 min and are too close together to be quantitatively resolved. To improve the resolution of the peaks, should you increase or decrease the amount of water in the mobile phase for the next run? Or is there not enough information? In a separate...

1. A students performed a TLC experiment on a mixture containing two compounds. However, he observed only one spot after visualizing the TLC plate with U.V. light. Give a possible explanation for the student observing only one spot. 2. TLC plates could be made of different particle size of silica. If one used a smaller particle size of silica in the TLC plate, how would that effect the results of a TLC experiment? Explain your answer.

1. Two fluorescent compounds A and B are present in a mixture. Using a spectrofluorimeter similar to the one used in this experiment, how would you determine the quantity of A in the mixture if- A absorbs radiation in a region where B does not. Both A and B absorb in the same region but A emits fluorescence at different wavelengths than B.

A firm produces a single output using two inputs x1, x2. Let p, w1, w2 be the prices. The production function f is C2 (twice continuously differentiable). Atp=5,w1 =1,w2 =2,theoptimalinputsarex∗1 =2,x∗2 =2. Ifεx1p =0.2 (the elasticity of x1 w.r.t. p), εx1w1 = −0.4 (the elasticity of x1 w.r.t. w1), and εx2 w2 = −0.5 (the elasticity of x2 w.r.t. w2 ), then, can you derive εx1 w2 , εx2 p and εx2w1?
