MMSC 407 Exam 1 Questions With
Complete Solutions
Spectrophotometry - CORRECT ANSWER✔✔-measurement of the | | | | | |
absorption of electromagnetic radiation of a substance at different
| | | | | | | | |
wavelengths of the spectrum | | |
tungsten light - CORRECT ANSWER✔✔-visible light
| | | | |
hydrogen/deuterium light - CORRECT ANSWER✔✔-UV light | | | | |
xenon/mercury vapor light - CORRECT ANSWER✔✔-UV light
| | | | | |
Monochromator - CORRECT ANSWER✔✔-a device that will select a| | | | | | | | |
narrow range of wavelengths of light from the continuous spectrum that
| | | | | | | | | |
is provided by the light source
| | | | | |
Interference Filters - CORRECT ANSWER✔✔-composed of 2 parallel
| | | | | | | |
sheets of half-silvered glass surrounding a core of MgF2; gets dirty easily
| | | | | | | | | | |
Prism - CORRECT ANSWER✔✔-narrow band pass; expensive
| | | | | |
, diffraction grating - CORRECT ANSWER✔✔-composed of a polished
| | | | | | | |
reflective surface onto which sharply defined, parallel groves have been
| | | | | | | | | |
etched; narrow band pass; best resolution; expensive
| | | | | |
cuvette shapes - CORRECT ANSWER✔✔-round, square
| | | | |
type of material - CORRECT ANSWER✔✔-clear glass, quartz, plastic
| | | | | | | |
Photomultiplier Tube (PMT) - CORRECT ANSWER✔✔-amplifies the | | | | | | |
primary signal; best and most sensitive photodetector
| | | | | |
Photo spectrometer quality control - CORRECT ANSWER✔✔-known-
| | | | | |
unknowns ran as patient samples with a known analyte concentration
| | | | | | | | |
Nephelometry - CORRECT ANSWER✔✔-measures light scattered
| | | | |
Turbidimetry - CORRECT ANSWER✔✔-a measure of amount of light
| | | | | | | | |
transmitted through sample | |
scattering - CORRECT ANSWER✔✔-redirection of radiation out of
| | | | | | | |
original direction of propagation, usually due to interaction with
| | | | | | | | |
molecules and particles | |
