Module code: CAPE203001 (b) Gas composition measurement: (i) Name one gas commonly measured online using non-dispersive infra-red (NDIR) absorption. (ii) Write the Beer-Lambert law expressing the concentration C of a gas in a sample cell of thickness L as a function of incident radiation on the cell and transmitted radiation from the cell (intensities $I_0$ and $I_t$). (iii) Which molecular energy level does IR absorption excite during NDIR gas analysis? (iv) In gas measurements of atmospheric pollutants using IR absorption, which of the analyser's characteristics needs to be large to provide an accurate measurement at very small concentrations (e.g. ppm levels)? (v) With respect to gas composition measurements of combustion exhausts by non- dispersive infra-red absorption, give an example of a component in the sample that may typically cause an undesirable increase in the readings. (vi) Is NDIR absorption a destructive or non-destructive method of analysis? (vii) Name one gas that may be measured by UV absorption. (viii) Which parameter allows the identification of a sample species in gas chromatography (GC)? (ix) Which aspect of a chromatogram can be used to quantify the concentration of an individual gas in a gas mixture? (x) Which physical phenomenon helps to carry out separation of the species in gas chromatography when a solid stationary phase is used in the column? (xi) In a flame ionisation detector ("FID"), write down the stoichiometric reaction that takes place. (xii) Name one hydrocarbon that is suited to GC-FID analysis. (xiii) What does the acronym TCD in GC-TCD stand for? (xiv) Which type of GC detector should be used to analyse O$_2$ content in a gas mixture? (xv) Which type of GC detector should be used to analyse C$_2$H$_6$ content in a gas mixture? (xvi) What online technique should be recommended to measure the concentration of nitrogen oxides online? (xvii) What online technique should be recommended to measure just oxygen gas concentration in a gas mixture? (xviii) Which two words are missing from the following sentence: "A mass spectrometer allows the measurement of species according to their... to... ratio". (xix) Name one component that makes up the three essential stages of a mass spectrometer. (xx) Give one advantage of mass spectrometry over other gas analysis techniques. [10 marks]
