THE UNIVERSITY OF THE WEST INDIES MONA DEPARTMENT OF CHEMISTRY CHEMICAL ANALYSIS II - CHEM3001 TUTORIAL PAPER 3 1. By considering  the operating principles and characteristics of the following GC  detectors, Electron Capture, Flame Ionisation and Thermal Conductivity Detectors,  indicate which detector would be best suited for the following gas chromatographic  separations: (i) evaluation of river water for the persistent organic pollutant aldrin;  (ii) preparative separation  of the anaesthetic eugenol from clove oil; (iii) analysis of the anti-inflammatory agent  β -caryophyllene in pimento berries. Give reasons for your choices. [15]                                     Aldrin eugenol β -caryophyllene 2. (a) With aid of diagrams, differentiate between an anionic and a cationic exchange
