Maintaining the Nano ITC
Maintaining the Nano ITC consists of purging the instrument, cleaning the filter, lubricating the o-ring, and
thoroughly cleaning the cells. This section provides information on these procedures.
Purging the Nano ITC
The Nano ITC features a sealed, nitrogen-filled canister surrounding the measurement cells in order to
ensure stable operation. If baselines become unstable, it may be necessary to contact TA Instruments for
service. Check for stability by operating the Nano ITC near ambient temperature, with the cells filled with
degassed water. Stirring should be switched off and the instrument allowed to settle. The peak-to-peak
noise amplitude of the baseline signal should be approximately 0.3 µWatts over a period of 10 minutes
(exclusive of any drift that may be occurring).
Important Note: The canister has been vacuum-purged and back-filled with dry nitrogen gas at the factory
before shipment, and will only very rarely be required again in the field. Contact TA Instruments for
service if the instrument does not maintain a stable signal as described above.
