Why is toluene in hexane used in uv calibration?
Toluene has clear absorption peaks at 266 nm and 269 nm. Hexane is only the solvent.
How would you use exposure in a sentence?
"Prolonged exposure to the sin's UV rays can be harmful.
What is the reported UV lambda max of Vildagliptin drug?
The reported UV lambda max of Vildagliptin drug is 254 nm.
Can UV rays go through wax paper?
yes, but it drastically reduces them
Why do you think remote controls for tv VCR and stereos use infared light rather than ultraviolet light?
Common household remote control devices typically use infrared light or radio frequencies.
Why is holmium used in uv calibration?
Holmium oxide is used as standard reference to check wavelengts.
Why holmium oxide is used in calibration of uv?
Because Only holmium can give sharp peaks in both UV and Vis range, Sharp peak is very rare in UV/Vis spectroscopy. It is very stable and doesn't absorb light at lower wavelength.
Why you are using kcl in the calibration of uv visible spectrophotometer?
how do you determine degree of deacetylation of chitosan using UV -vis spectrophotometer
Why limit of stray light perform in uv calibration and how?
To check external interference of light
Why potassium chloride used for calibration of limit of stray light in UV?
Cuz we dont know
Why is Erbium perchlorate is used in calibration of HPLC?
Erbium has a strong absorption in uv and visible range, It is used in HPlc calibration for the wavelength accuracy verification of the PDA detector.
How do you filter uv radiations?
We cannot filter too much UV rays. This is the work of ozone in our atmosphere.
What is holmium used for?
Holmium is a rare earth chemical element. It has a very high magnetic strength and hence is used in the strongest of magnets. It also absorbs neutrons and hence is used in the control rods of nuclear power stations.
Do light bulb emit UV?
Florescent lams do ... museums use a tubular UV filter over those bulbs to prevent damage to two-dimensional paper ephemera.
Does the ozone layer filter UV radiation?
Yes, it is the only thing. It filters the UV.
If the ozone is covered in a glass box protecting it from disappearing will it still filter out UV rays?
Ordinary glass will filter out UV rays by itself. So you will get the combined filtering of the glass and the ozone reducing the UV ray intensity.
Why1.2 percent water solution of potassium chloride used in UV calibration?
The solution of potassium chloride is used to evaluate the stray light.
