Absorbance Wavelength

(1/2) > >>

KanizRonakSultana:
Wondering, if anybody could help me out to find the absorbance wavelength of pure Vegetable Glycerin?
Thanks in advance.

Borek:
Standard procedure is to record the spectra and choose whichever wavelength suits your needs best.

Orcio_87:
For a quantitative measure, the best wavelength is the one which gives the highest absorbance.. if there no other compounds in the sample absorbs at the same wavelenght.

morphism:
First of all, you should get the pure Vegetable Glycerin's spectra and after that use some software or any manuals/procedures "absorbance - frequency". It should be clear, my friend.

Babcock_Hall:
Why do you need to do absorption spectrophotometry on glycerin?  What are you trying to accomplish?
