Issue

The iCAP Pro Duo is experiencing a recurring issue with humidity causing the detector to shutdown. When the humidity increases, the detector shuts down, leading to disruptions in the workflow. The issue was initially identified when the humidity reached 15%, and subsequent attempts to bypass the in-line argon filter resulted in the temperature dropping to -45°C. The customer has been monitoring the issue and has implemented temporary measures, such as purging the camera and using the engineer's purge. However, a permanent solution is required to prevent further disruptions.

Resolution

To resolve the issue of humidity causing the detector shutdown on the iCAP Pro Duo, follow these steps:

  1. Replace the molecular sieve: Since the humidity increase is directly impacting the detector, replacing the molecular sieve is recommended. The molecular sieve helps absorb moisture and maintain a stable environment within the instrument. Follow the manufacturer's guidelines or consult the instrument's documentation for specific instructions on how to replace the molecular sieve.

  2. Perform a thorough cleaning: Before installing the new molecular sieve, ensure that the instrument is clean and free from any debris or contaminants that could affect its performance. Use appropriate cleaning agents and follow the manufacturer's instructions for cleaning the instrument.

  3. Calibrate the instrument: After replacing the molecular sieve and cleaning the instrument, perform a calibration to ensure accurate and reliable measurements. Follow the calibration procedures outlined in the instrument's documentation or consult the manufacturer for specific instructions.

  4. Monitor and maintain humidity levels: Regularly monitor the humidity levels in the environment where the instrument is located. Implement measures to control and maintain the humidity within the recommended range for optimal instrument performance. This may include using dehumidifiers or maintaining a controlled laboratory environment.

  5. Contact technical support if the issue persists: If the issue of humidity causing detector shutdowns persists despite the above steps, contact the manufacturer's technical support for further assistance. Provide them with detailed information about the issue and any relevant troubleshooting steps taken.
