(a) Give a brief overview of chromatographic separation mechanisms. Your answer should include reference to adsorption, partition, ion exchange, gel filtration and affinity Indicate the mechanism most relevant to Gas Chromatography (GC). chromatography. (b) Using a drawing, describe in detail the structure of a typical column used for GC. Make sure to mention: (i) the dimensions and materials of the column itself and (ii) the chemical nature of any one common chromatographic stationary phase that could be mounted inside the column. (c) Explain why careful temperature control of the column is very important in GC and why the use of temperature programming can be advantageous.

Consider the following method for the analysis of cocaine (MW 303.35) powder. "Dissolve about 600 mg of cocaine, preciously dried and accurately weighed, in 50 mL of glacial acetic acid, add I drop of crystal violet TS, and titrate with 0.1 M perchloric acid VS to a green endpoint. Perform a blank determination, and make the necessary correction" Calculate the percentage purity of the cocaine sample from the data below. Show your reasoning clearly and record your final answer to four significant figures. CH₂ ● Cocaine powder weighed = 606.3 mg Concentration of HCIO3=0.09978 M H₂C-N- Volume HCIO3 required for the assay mixture = 19.97 mL ● Volume HCIO; required for blank determination = 0.059'mL
What is the principle of the instrumental method of analysis of Kool Aid Chromatography? Describe the components' (allura red and brilliant blue) separation of Kool Aid based on mobile and stationary phases.
A dual beam UV-visible spectroscopy was used to determine the levels of Fe(II) in the run-off water of a local mine using the ferrozine assay (i) During a check of the instrument a step-like feature at 360 nm was observed in spectrum of the standard. Suggest what may give rise to this with reference to the instrument configuration and comment on how it may be remedied. (ii) The molar absorptivity of the [Fe(Ferrozine)3]2+ complex is 27900 cm−1 M−1 at 562 nm in aqueous solution (pH 5.5). If the EU maximum contaminant level for Fe is 200 ug /L and the contract required detection limit is 100 ug/L, comment on the suitability of the assay for the detection of iron. (iii) Determine the sample range, in terms of concentration and ppm, of Fe(II) that can be confidently analysed by UV-visible spectroscopy using a 1 cm cuvette. Explain with reference to an appropriate equation and solution phenomena, the origin of the limitations that define this range

In a 1.10 m gas-liquid chromatographic column the following results were obtained: air, 18.0 s; methyl acetate, 1.98 min.; methyl propionate, 2.24 min; methyl n-butyrate, 7.93 min. The base widths of the last three peaks were: 0.19; 0.23 and 0.79 min, respectively. Calculate the theoretical number of plates and the plate height of each column.
The following statements are true for any chromatographic analysis except: The analyte component interacting most strongly with the stationary phase elute faster than those with weaker interactions. On the other hand, those with least interaction with the mobile phase elute the slowest. Interactions between mobile phase-analyte - stationary phase can be both chemical and physical in nature. Chromatography is a separation technique. XPS can be used for the following analyses except-* Contamination in the surface or the bulk of the sample Functional group of the sample Binding energy of electronic states Thickness of materials Density of electronic states A technique used in observing trace elements, isotopes and atomic monolayers based on the secondary ions that are ejected from the sample. XRD AFM SEM SIMS ELLIPSOMETRY XPS NLO
