Short as possible GAS ANALYSIS ppt Flashcards
What are the different types of organic and inorganic Gas Analysis
Gas liquid chromatography INFRARED ANALYSIS Mass spectrometry Raman Scattering Piezoelectric analysis Interferometry-refractomer
All electromagnetic radiation, thus visible light, ultra violet light, and infrared light may be ______, _______, or ______ by matter
reflected transmitted absorbed
Oxygen, CO2, and Anesthetic agents are what ?
Matter
Electromagnetic radiation can be converted into other forms of energy such as ____, _____, and _______
electricity (gas discharge) Heat (incandescence) Chemical (Photoluminescense)
Types of O2 analysis systems
GALVANIC CELL (FUEL CELL) POLAROGRAPHIC ELECTRODE PARAMAGNETIC O2 SENSOR fluorescence-quenching pH optode
Galvnic (fuel cell)
- Membrane permable to what?
- At the cathode ____ molecules are reduced to H+
- At the Anode____ ions give up electrons
- an electron flow b/t the lead ____ and the gold _____ is generated in a K+ hydroxidesolution
- Gasses (not liquid)
- oxygen
- hydroxide
- anode cathode
Galvnic (fuel cell)
Main concept of Galvanic fuel cell
Continual consumption = limited life
Clark polarographic Oxygen electrode
- Consist if a _____ source and a _____ meter connecting platinum and silver electrodes
- the electrodes are immersed in an _______ cell

I give up just doing the highlightes he said I am running out of time sorry for this…
sorry again
what is the only thing that exist in the world
energy (matter is just energy at rest)
Infrared Absorption analysis
molecules may absorb infrared light if they are _____ and _____
Polyatomic and asymetric
Infrared Absorption analysis
advantages
anesthestic gasses can be measured
Infrared Absorption analysis
disadvantage
symmetric molecules such as O2, N2 and Helium will not be detected
What is the #1 way we measure anesthetic gases
(don’t say mass spec)
what is needed for mass spectrometry
a dedicated room due to large size of equipment
how does infrared absorption analysis
the freq absorbed tells you what gas, the amount absorbed tells you how much gas in absorbed
difference b/t raman scattering and infrared
raman- looks at freq of what is changed
Infrared looks at freq missing
what is the 2nd most common monitoring system for gases
raman scattering
advantages of Raman scattering
real time results
accurate
identifies all VAAs
only reuirs molecules to be polyatomic (can identify O2 and N2O with sole exception)
disadvantages of Raman scattering
*******
the majority of gas analyzers used in the operating rooms are _____ ____ or _____ _____ for oxygen ,measurement
galvanic cell or paramagnetic sensors
the main analyzer for N20, CO2, anesthetic Gases in the OR is ______ _______ _______ ______
What system uses
O2, anode, Cathode, spontaneous electrical current, continual consumption
Galvanic Cell (fuel cell)
What O2 system uses
O2, anode, cathode, applied electrical current, no current = no consumption
Polarographic electrode (clark)
What O2 system uses
O2 magnetic feild attraction, pressure differences, transducer
Paramagnetic O2 sensor
What O2 system uses
O2 absorption of excited electron energy in fluresent dyes preventing photon emission
fluoresence quenching
What O2 system uses
uses the fluorescent quenching principle applied to hydrogen ions
pH optode
Which CO2 measurment system uses
uses the fluorescent quenching principle applied to hydrogen ions
pH optode
Which CO2 measurment system uses
pH sensitive glass electrode, electrolyte cell, CO2-permeable membrane, carbonic acid, pH change is proportional to Co2 change
Severinghous PCO2
thats it chicken fuckers
