Conductivity Testing
Conductivity measures a substance’s ionic strength and helps confirm that reagent concentration stays within range, avoiding skewed results. Learn more about conductivity testing for custom-made reagents before release.

Considerations and Limitations of Conductivity Testing | |
|---|---|
Temperature of the Solution | Conductivity is temperature-sensitive, with higher temperatures increasing conductance. Ensure temperature compensation for consistency. |
Concentration of the Solution | Extremely concentrated solutions may affect the outcome of the conductivity reading and should be diluted from a 1X to a 10X solution prior to performing the conductivity test. |
Ionic Strength of Reagents Ambient Gases | Ambient air can influence conductivity, particularly carbon dioxide (CO2) as it forms the carbonic acid (H2CO3), which dissociates into ions in solution. |
