3.2 OPTIONAL TRAPS
Optional traps (described in Section 2.1, Figure 2) must be maintained for optimal sys-
tem performance. The ANT100 utilizes neutralizing solutions which exhibit a color
change when depleted. Ammonia Neutralizing Solution (ANS121) changes from pink to
blue; Neutralizing Solution for Acids (NSA300TF) changes from blue to pale yellow
when depleted. Replace solution bottle when a color change is observed. If using solid
chemical cartridge with DTK120R, the DC120A cartridge for acids turns white to blue;
change when depleted. DC120R cartridge for radioactivity/organics has no color indica-
tor; replace monthly.
3.1 EMPTYING THE GLASS CONDENSATION FLASK (cont’d)
NOTE: If the Refrigerated Vapor Trap is not needed for several weeks, you
may wish to shut it off between uses. Before switching on again,
always remove the used glass vessel and replace with a clean, dry
trap. Check the condition of the CryoCool; if a layer of water is
visible under the CryoCool, remove with a pipette. Failure to follow
these precautions may cause the glass vessel to break when the
trap returns to operating temperature.
NOTE: Periodically check Flask Cover for signs of wear or perishing, and
replace if necessary.
