Visual Inspection: Frequently inspect the electrode cap for any signs of wear, cracks, or other damage. Even minor damage can compromise the performance of the electrode and affect the accuracy of your measurements.
Check for Residue: Examine the inside of the electrode cap for any buildup of sample residues or oxidation products, which can occur during the combustion process. Such residues can contaminate future samples and affect analysis results
Physical Damage: Replace the electrode cap immediately if it shows any signs of physical damage, such as cracks, warping, or deformation. A damaged cap cannot protect the electrode properly and may lead to inaccurate results.
Persistent Contamination: If the electrode cap becomes contaminated with residues that cannot be fully cleaned or if contamination occurs frequently, it might be time to replace the cap.
Wear and Tear: Over time, the electrode cap may wear out due to repeated exposure to high temperatures and corrosive environments. If the cap no longer fits securely or shows signs of excessive wear, it should be replaced.
