Objectives

  1. Run FTIR on crosslinked glutaraldehyde films dried and weighed on 10/2/12
  2. Weigh and dry more crosslinked glutaraldehyde films in preparations for running FTIR
  3. Run DSC on crosslinked glutaraldehyde films dried and weighed on 10/2/12
  4. Finish running UV-vis on porphyrine solutions

UV-vis

  • The general protocol for UV-vis was followed

Samples ran UV-vis on:

  1. PVOH(22K) 1.0067g+1mL GA+1mL porphyrin fixant solution from crosslinking
  2. PVOH(22K)+0.5mL GA+1mL porphyrin prepared 10/26/2012 fixant solution from crosslinking
  3. PVOH(22K)+1.0mL GA+1mL porphyrin prepared 10/24/2012 fixant solution from crosslinking
  4. PVOH(22K) 1.05225g+0.5mL GA+1mL porphyrin prepared 10/26/2012 fixant solution from crosslinking


Notes:

  • All obtained spectra will be uploaded
  • Baseline was run with an empty quartz cuvette
  • Blank was run with HPLC grade H2O
  • At first the samples were run under the kinetics option of the Shimadzu UV-2550 spectrophotometer. Must remember to change the option
