Solved in 3 steps
- What are the functions and procedure of analysis of many volatile organic molecules by using Gas chromatographyWhich properties would be ideal in selecting the compound to be used as a primary standard for quantitative volumetric analysis?The identity of a volatile petroleum residue is determined by the (size, pattern) of its gas chromatogram
- Describe chromatography analysis, the two essential phases used in paper chromatography and provide an example.The required mobile phase for the analysis caffeine in soft drinks in liquid chromatography are methanol and water. What class of methanol and water must be used? Kindly explain the answer.You are carrying out an experiment by analysing alcoholic drinks by gas chromatography. Why is Gas chromatography the best technique used for this analysis? Why is Carbowax a suitable stationary phase for this analysis? What gases are used and what is their purpose and source?
- 2. What is the basis for the separation of components of mixtures by paperchromatography?The height of three peaks; A, B, and C obtained in a gas chromatogram are 20.6 mm, 17.5 mm and 40.6 mm. The width of the peaks, at half height, are 4.4 mm, 4.0 mm and 3.9 mm, respectively. Calculate the percentage composition of A in the sample.hree components in a mixture have varying distribution constants between the mobile phase and the stationary phass One of the components has a very low distribution constant, Would this component likely elute first or last and how would you design an experiment or modify the components of the separation to make it perform in the opposite manner?
