UV-Vis Flashcards
1
Q
What is Beer-Lambert Law
A
Amount of energy absorbed by a solution is proportional to the path length and concentration
2
Q
How to get a reliability and best practice
A
UV-Vis spectroscopy experiments and reading will be repeated
3
Q
How to measure the transmittance
A
Divide the intensity spectrum of light transmitted through through a sample by intensity spectrum of light through the blank
4
Q
What is absorbance
A
optical density, amount of light absorbed by the object and can be expressed as follows
A=-log (T)
5
Q
ULight scattering
A
Light scattering often caused by the suspended solid in liquid samples, which may cause serious sample will scatter light, resulting in irreproducible results
