Troubleshooting the Ampule QC
Use the following recommendations to help resolve issues with failed QC
performed from an ampule:
• Perform only one QC analysis for each ampule.
Performance claims are based on one QC analysis per ampule.
• Always use the Quick adapter when analyzing QC samples.
• Analyze the QC material immediately after opening the ampule.
Prolonged contact with the atmosphere affects pH, pCO
2
, and pO
2
results.
• Ensure that the correct target ranges are defined in Setup.
• Store QC material at a constant temperature.
• Do not handle ampules excessively.
Variation in results may occur due to changes in temperature.
• Do not use expired QC materials.
• Do not analyze QC materials that contain bubbles.
• Use the correct level of QC material that is scheduled for analysis.
