WebJan 3, 2024 · If the optical density of the sample is greater than 1.0, dilute the sample 1:10 with deionized water and read the optical density again. (The linear relationship between the OD 600 and cell density is lost when OD 600 values exceed 1.0) Record the new value in your lab notebook, noting how you diluted your sample. Dispose of all cell material ... WebLight refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. For example, when light travels from air into …
WebBut when light moves through a more familiar medium like air, it moves more slowly due to the interactions of individual photons with the molecules in the material. In general, the more optically dense the medium, the slower the light will move. So what happens to the light when it goes from one medium to another? Light changes speed WebThe index of refraction of the oil (and of the glass, too) is a function of temperature. This demonstration will work better on some days than others. Going Further Index of …
Webthe absorption issue and made it possible to measure high optical density crude oils with typical Visible-NIR wavelengths. Surface-Enhanced Raman Spectra (SERS) can also be measured. SERS can provide additional useful information, especially to some applications such as downhole fluid analysis, where confirmation of the hydrocarbons presence is
