• Consider atmosphere compatibility when selecting analysis conditions

Proper Installation Steps:

1. Pre-Analysis Preparation:
   • Inspect lid for any cracks or damage before use
   • Clean lid surface with appropriate solvent (isopropanol recommended)
   • Allow to air dry completely to prevent contamination
2. Sample Loading:
   • Place sample in compatible alumina crucible
   • Ensure sample mass is within recommended range (5-50mg)
   • Distribute sample evenly across crucible bottom
3. Lid Placement:
   • Gently place lid on crucible ensuring proper alignment
   • Check for complete contact around crucible rim
   • Avoid applying excessive pressure that could damage ceramic
4. System Loading:
   • Carefully transfer sealed crucible to TA Instruments sample holder
   • Ensure proper positioning for optimal thermal contact
   • Verify atmosphere selection matches lid compatibility

Safety & Handling Precautions:

• Temperature Safety: Use appropriate handling tools when working with high-temperature applications
• Chemical Compatibility: Verify sample compatibility with alumina before analysis
• Storage: Store in clean, dry environment to prevent contamination
• Disposal: Follow laboratory protocols for ceramic waste disposal
• Quality Check: Inspect for damage after each use cycle

Maintenance & Cleaning:

• Clean with mild detergent and deionized water after each use
• For stubborn residues, use ultrasonic cleaning with appropriate solvents
• Avoid abrasive cleaning materials that could damage ceramic surface
• Store in protective containers to prevent mechanical damage
• Replace if any cracks or chips develop
