After each session of illumination we measured UV-VIS absorption spectrum of the sample using Shimadzu UV-1900.
I also checked the UV absorbance of the BPA dissolved in Ethanol and I got two specific UV of the absorbance of DMSO. Although I have diluted the samples (1500 time) in the DMSO I am wondering.
In chemistry, absorbance or decadic absorbance is the common logarithm of the ratio of incident to transmitted radiant power through a material.

HPLC Dimethyl sulfoxide (DMSO) is purified, dried, and distilled in glass and guaranteed for lot-to-lot consistency and low UV absorption. HPLC grade Dimethyl.
Its absorbance spectrum shows absorption of blue and red light, but not of the green part of light. Why measure absorbance? In biology and chemistry, the principle of absorbance is used to quantify.
Ultraviolet absorbance cannot be measured on the Spectronic instruments, which do not have UV lamps and UV optics. 6 UV Absorbance SOP ver1.doc. UMass Environmental Engineering Program.
Measuring Intrinsic Protein Fluorescence with Modular Spectroscopy Tools – Its absorbance spectrum shows a peak at ~280nm originating from its indole group. The absorption spectrum of tyrosine is similar to that of tryptophan and has optimal excitation near 274nm. These.
At this point either DMSO or HFIP was utilized to dissolve the peptide film. DMSO was used for the bulk of the experiments but it has strong UV absorption, precluding its use for CD. To solubilize the.
