* Using a Shimadzu UV-2550 spectrophotometer, spectra of four concentrations of porphyrin solutions were taken: | |||
* Wavelength range = 200 - 800nm | |||
* Slit width = 1.0nm | |||
==UV-Vis Analysis Notes== | |||
* The baseline was conducted with nothing in the cell. | |||
* For solutions at concentrations 944.5nM and 94.45nM, two peaks were visible at 410nm and 430nm. | |||
* The 9.445nM was not concentrated enough to produce any peaks. | |||
* The 944.5nM solution displayed several more peaks past 500nm, producing more useful data. | |||
