DSC 4000 Maintenance
The DSC 4000 needs little routine maintenance other than proper treatment as a sensitive
electromechanical device.
Since the sensor disk is the hottest component in the furnace area, it will usually remain
clean and free of condensates. However, samples may ooze out of sample pans or be
accidentally spilled onto the sensor disk. Such materials should be removed at low
temperatures whenever possible by using tweezers or moistened cotton swabs.
Solvents should not be placed directly on the sensor. Moisten a cotton swab or a tissue with
solvent; then clean the sensor or upper portion of the furnace wall with the swab.
Any residual sample that has carbonized may remain on the sensor disk after it has been
cleaned with a solvent. To remove the residue, gently scrub the sensor with a fiberglass or
nylon brush. Be careful not to exert excessive force when scrubbing the sensor since it can
be damaged. The sensor must be as clean and flat as possible for proper operation.
To avoid contaminating the furnace, use a purge gas at proper flow rates. If the furnace
becomes contaminated, clean it as soon as possible.
Cleaning and Decontamination
Before using any cleaning or decontamination methods except those specified by
PerkinElmer, you should check with PerkinElmer that the proposed method will not damage
the equipment.
