WebbThe Raman map created by the LabRAM provides more detailed information on the chemical distribution of the polymer species in this blend than could be achieved with a TV image and a Raman microprobe without mapping capabilities. One sees that the fields with the purest PBT (red) are larger than the regions with pure PE (blue).
