Handling System Components
Listed in this section are guidelines for handling system components.
Calibration Standard(s)
These guidelines are for handling the calibration standard(s):
• Wear latex or nitrile, powder-free gloves to prevent transfer of oil from your hands
• Do not drop the standard(s) into the sample cup; allow the standard(s) to roll gently
into the cup to prevent denting the cup
• Always return the standard(s) to their case; standard(s) are unit-specific
Sample Chamber Cap
These guidelines are for handling the sample chamber cap:
• Wear latex or nitrile, powder-free gloves to prevent transfer of oil from your hands
• Keep the cap on the sample chamber except when inserting or removing the sample
cup. When left uncapped, the sample chamber temperature may become unstable and/
or water vapor will adsorb on the inner surface of the chamber. Either of these
conditions can affect analysis results.
• Avoid laying the chamber cap on a work surface; debris may collect on the greased
surface of the O-ring which can also affect analysis results
• When multiple analysis modules are connected, never interchange sample chamber
caps; caps are unit-specific
Greasing the Chamber Cap O-ring
Grease the O-ring in the sample chamber cap as described below. Wear latex gloves to prevent
contaminating the grease with oil from your fingertips.
1. Turn the chamber cap counterclockwise and lift it from the chamber.
2. Place the chamber cap on a clean surface, with the O-ring side exposed.
3. Place a small amount of Dow Corning High vacuum grease (or equivalent) on your index
finger.
Apply the grease sparingly; too much grease may alter cell volume, while too little
grease results in an imperfect seal and leaks.
