5. ACCESSORIES
5.1. Sample cell - ASM1398
The sample cell is a ~5ml vessel attached at the end of the probe for performing manual
sample analysis or used as part of a probe cleaning procedure. It is fixed in place using a tri
clamp that locates over the rear of the sample cell and two semicircular collars that fit around
the probe; the clamp does not need to be tightened with significant force. For volatile
substances it is recommended to keep the plugging cap in place during use.

5.1.1. Maintenance
Inspect the O-ring regularly and replace if it has visually degraded, whether through swelling
or other damage; use plastic forceps to remove the O-ring. This is particularly important if the
chemistry that you are analysing is known to cause swelling of the O-ring elastomer. In any
case, replace O-rings annually.
5.1.2. Cleaning
The sample cell may be cleaned using standard laboratory cleaning practices, as appropriate
for your reaction. Also ensure the ATR element has been thoroughly cleaned and dried before
use of the sample cell.
