Open the sample press by twisting the knurled nut until the
sample press tip is elevated slightly from the diamond ATR
surface (see Figure 9).
The diamond sampling window should be visible at this point.
Place a small amount of material to be measured on the diamond
ATR crystal. The crystal is the clear, circular shaped material
held in place by the surrounding metal disk.
Ensure that the sample covers the entire surface area of the
diamond crystal.
In the case of a volatile sample, larger amounts of sample can be
applied without concern of leakage or damage to the instrument.
However, using the smallest amount of sample possible will ease
in the cleaning process.
