Figure 3-3: Absorbance Spectrum of Polystyrene
If you are using an integrating sphere:
a) Set the scan count to 8 using the field adjacent to the
button.
b) Place a reflectance reference on the integrating sphere (e.g. Spectralon
TM
or roughened gold).
c) Verify that the
button is depressed and press the
button. A background spectrum will be collected.
d) Place a vial filled with a solid (e.g. sugar) over the opening of the
integrating sphere.
e) Press the
button and then press the
button. The
spectrum will be collected and displayed (Figure 3-4). The shape of the
spectrum will depend on the wavelength range of the spectrometer and
the sample that is employed. At this juncture, the critical thing is to view a
spectrum that is different than the background spectrum collected above.
