Answer to Question 1

ANS: C
The paramagnetic analyzer uses the physical principle of paramagnetism to measure oxygen con-centration. Galvanic and polarographic analyzers use chemical reactions to measure oxygen con-centration, and electrical analyzers use thermal conductivity.

Answer to Question 2

ANS: C
An electrical analyzer uses a Wheatstone bridge setup and monitors the changes in current flow as it relates to oxygen concentrations. The Wheatstone bridge can generate a significant amount of heat and therefore is dangerous to use in the presence of flammable gases, such as anesthetic gases.
