A. Katharometer
B. Paramagnetic
C. Mass spectrometer
D. Fuel cell
E. Van Slyke apparatus via Haldane method

Answer 1

e - they are 2 seperate techniques, both used for O2 analysis tho

Question 2

Severinghaus CO2 electrode:
A. KCl and NaHCO3 as electrolyte solutions
B. CO2 sensitive glass
C. Electrical signal directly proportional to log pCO2
D. Platinum electrode
E Glass permeable to H+

Answer 2

a

Question 3

EC09 [Sep90] [Mar92] [Aug92]
Concerning polarographic oxygen analysis:
A. Clark electrode responds to partial pressure of oxygen
B. 0.6 volt (600mV) between electrodes
C. N2O & moisture condensation do not affect result
D. Relies on oxygen diffusion through PVC membrane
E. Requires less maintenance then fuel cell

Answer 3

b

responds to O2 concentration then calculates ppO2, not affecte by moisture, more maintenece than fuel
