synthetic diamond, which is extremely chemically-resistant. However, it is still
possible the diamond or metal mounting plate can be damaged by extreme
samples. Only measure samples with a pH between 1 and 14. Do not leave
extremely acidic samples on the metal mounting plate for an extended time.
Although diamond is a very hard material, the ATR window is relatively thin and

can crack under extreme pressure conditions. Ensure that the sample makes
contact with the entire surface area of the diamond and not just a point within
the diamond. Avoid using the sample press on samples that may be sharp or
pointed.

Using the solid sample ATR press

The 4200 FlexScan FTIR ATR system is offered with an optional
sample press attachment that is removable when not required. The
sample press enables improved measurement of solid or powder
samples. The press ensures that the sample is in good contact with
the diamond ATR sample interface, which ensures the best possible
results for these sample types. The press is designed to deliver
15 pounds of force to the sample or over 2500 pounds per square
inch of pressure. It is not for use with liquids, gels or pastes, as the
press may come directly in contact with the IR energy and alter the
results. These types of samples make good contact without the use of
a press.
