What chemicals are known to affect the probe coating or measurement accuracy?
The glass is susceptible to long-term attack by high-alkalinity environments and HF (hydrogen fluoride), as well as to severe physical abrasion. The glass is immune to common organic solvents. In the event that the coating is damaged or destroyed, the probe can be re-coated at a nominal charge. We also provide witness samples (coated glass cover slips) for testing susceptibility to unusual or hazardous solvents, or to conditions we can’t reproduce in our lab. Measurement accuracy is affected by compounds that competitively quench the fluorescence. For details on each sensor coating’s chemical compatibility, click here.
