spectrum
1. When the background spectrum has been acquired, insert the sample in
the sample holder or sampling accessory.
For an FT-IR series spectrometer:
• For MIR, use the polystyrene sample supplied with
the spectrometer (see Figure 1-8 below).
• For NIR, do not use the polystyrene sample. Instead, place an
ordinary plastic bag over the sample holder.
For another model of spectrometer, use a sample of the appropriate type.
