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
Q

advantages of Raman scattering

A

real time results

accurate

identifies all VAAs

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

21
Q

disadvantages of Raman scattering

A
22
