1μM Rhodamine 6G Dye Concentration (90:10)

  M1V1 = M2V2
  1μM (RG6)x 10mL = (92μM)V2    V2 = 109μL

90:10 110% CEC NaMT w/ DMHXLBR 0.01090 0.09340 40 92 109

Notes

  • Unfortunately, DSC samples were not taken before the Rhodamine 6G dye was added to each sample; therefore, these samples must be remade.
