Analytical Chemistry June 26,2006
01.Explain the following terms:(12%)
a)Donnan equilibrium p.644
b)ion pair chromatography p.649
c)selectivity coefficient p.644
d)split and splitless injection p.588
02.Describe a two-column system of ion chromatography for the analysis of acid
rain. For the above system, state the advantage where cation exchange
membrane is used instead of the suppressor.(12%)
p.648
03.Consider a capillary electrophoresis experiment conducted near pH 9, at
which the electrophoresis flow is stronger than the electrophoretic flow.
Drow a picture of the capillary, showing the placement of the anode, cathod,
injector and detector. Show the direction of electroosmotic flow and the
direction of a cation and an anion. Show the direction of the net flow.(15%)
p.658
04.Ionisation methods for the mass spectrometry include the following:
Atomospheric Pressure Chemical Ionisation(APCI), Chemical Ionisation(CI),
Electron Impact(EI), Electrospray Ionisation(ESI), Fast Atom Bombardment
(FAB), Field Desorption/Field Ionisation(FD/FI), Matrix Assisted Laser
Desorption Ionisation(MALDI), and Thermospray Ionisation(TSP). Illustrate
any two of them.(12%)
(*編按：劉老師的ionisation=ionization。她從上課一直寫錯到出考卷...||*)
自己看第22章。XD
05.There are a number of mass analysers currently available, the better known
of which include quadrupoles, time-of-flight(TOF) analysers, magnetic
sectors, and both Fourier transform and quadrupole ion traps. Briefly
describe how a magnetic sector mass spectrometer works.(10%)
p.518
06.The following figure shows the extration of metal ions by dithizone into
CCl4. What infotmation can be given from the figure?(10%)
圖請參考 Quantitive chemical analysis/Daniel C. Harris/6ed Figure 23-4
p.552
07.Describe the principle upon which each of the following gas chromatography
detectors are based (a) thermal conductivity (b) flame ionization (c)flame
photometric (d) sulfur chemiliminescence.(12%)
p.591&593
08.Illustrate how solid phase microextration can be used for the sample
preparation.(8%)
p.596
09.Explain the following mass spectrum.(7%)
圖請參考 Quantitive chemical analysis/Daniel C. Harris/6ed Figure 22-8
p.524
10.Explain how a neutral molecule can be concentrated on column in a micellar
electrokinetic chromatography.(10%)
圖請參考 Quantitive chemical analysis/Daniel C. Harris/6ed Figure 26-32
p.670
