I give up just doing the highlightes he said I am running out of time sorry for this...

sorry again

11

what is the only thing that exist in the world


energy (matter is just energy at rest)

12


Infrared Absorption analysis

molecules may absorb infrared light if they are _____ and _____


Polyatomic and asymetric

13


Infrared Absorption analysis

advantages

anesthestic gasses can be measured

14

Infrared Absorption analysis

disadvantage

symmetric molecules such as O2, N2 and Helium will not be detected

15


What is the #1 way we measure anesthetic gases

(don't say mass spec)

16


what is needed for mass spectrometry


a dedicated room due to large size of equipment

17

how does infrared absorption analysis

the freq absorbed tells you what gas, the amount absorbed tells you how much gas in absorbed

18


difference b/t raman scattering and infrared


raman- looks at freq of what is changed

Infrared looks at freq missing

19


what is the 2nd most common monitoring system for gases


raman scattering

20


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)

21


disadvantages of Raman scattering

22
