Instruments that measure Spectrophotometry
electromagnetic
radiation
Which instrumentation is Spectrophotometry
paired with Beer's Law?
2 types of Atomic absorption
spectrophotometry Fluorometry
Measures concentration Atomic absorption spectrophotometry
by detecting the
absorption of
electromagnetic
radiation by atoms
Measures concentrations Fluorometry
of solutions that contain
fluorescing molesures
Chemical energy Chemiluminescence
produces excited
intermediates that decay
to a ground state with the
emission of protons
Amount of light scatter Nephelometry
by small particles is
measured at 90 degrees
, Decrease in amount of Turbidimetry
light transmitted at 180
degrees
Particle's ability to block Turbidimetry
light is dependent on the
concentration and
particle size
How well a measurement Accuracy
agrees with an accepted
value

measurements agree with
each other
Ability to detect small Sensitivity
concentrations of a
substance
Ability to measure only Specificity
the substance of interest
(no interfering
substances)
