Q

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

A

sorry again

11
Q

what is the only thing that exist in the world

12
Q

Infrared Absorption analysis

molecules may absorb infrared light if they are _____ and _____

A

Polyatomic and asymetric

13
Q

Infrared Absorption analysis

advantages

A

anesthestic gasses can be measured

14
Q

Infrared Absorption analysis

disadvantage

A

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

15
Q

What is the #1 way we measure anesthetic gases

(don’t say mass spec)

A
16
Q

what is needed for mass spectrometry

A

a dedicated room due to large size of equipment

17
Q

how does infrared absorption analysis

A

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

18
Q

difference b/t raman scattering and infrared

A

raman- looks at freq of what is changed

Infrared looks at freq missing

19
Q

what is the 2nd most common monitoring system for gases

A

raman scattering

20

real time results

accurate

identifies all VAAs

only reuirs molecules to be polyatomic (can identify O2 and N2O with sole exception)
