Analytical techniques Flashcards
1
Q
chromatography
A
used for separating complex mixtures of compounds
2
Q
rf formula
A
distance it travels / distance from origin
3
Q
electrophoresis
A
separating proteins (DNA and RNA)
4
Q
negatively charged moves…
A
to positive terminal (anode)
5
Q
positively charged moves…
A
to negative terminal (cathode)
6
Q
mass spectrometry
A
mass to charge ratio of ions -> molecules split to find whole compound
7
Q
x-ray crystallography
A
EM waves pass through a molecule to show e- densities and bonding -> can figure out molecule
8
Q
infrared
A
absorption of frequencies by a molecule -> specific frequencies have different bonds
