We know by now that pH and conductivity are critical aspects of numerous industrial processes. While many processes may measure one or the other, it’s highly common that a process requires the measurement of both to determine if a sample is contaminated or properly conditioned for a process’s needs. In these cases, it’s important (and quite simple) to understand the relationship between the two parameters and how they affect the process they influence.
It’s All About the Ions
There is a correlating relationship between pH and conductivity. Though the two parameters do not inherently influence each other, their correlation arises from the influence of free-flowing ions on both. In other words, pH may not increase simply because conductivity does, and vice versa, however, both values could increase depending on the presence of ions in a solution.
pH is the measurement of hydrogen ionic activity. Conductivity is the measurement of those and other ions’ ability to produce an electric current. Thus, the relationship can be seen here. The more ionic activity present, the higher the conductivity. If those ions happen to be hydrogen ions, pH will therefore increase.
Where It Matters
pH and conductivity are extremely important to quality control of certain processes such as those dealing with Ultra-pure water (UPW). UPW must contain very little or virtually no dissolved ions. Monitoring pH and conductivity in applications that require the use of UPW allows for early detection of contamination. These measurements allow technicians to take corrective actions before problems escalate. Additionally, industries must comply with stringent water quality standards. Accurate pH and conductivity measurements help meet regulatory requirements while maintaining high product quality.
Furthermore, both measurements play critical roles in equipment monitoring, especially in heavy industry processes like semiconductor production and power generation applications. Preventing corrosion and scaling in these processes is essential, and pH and conductivity measurements can serve as indicators of maintenance needs and cleaning necessities. Being knowledgeable of your process needs regarding pH and conductivity reduces the risk of defects and inefficiencies. Proper pH and conductivity monitoring helps technicians protect expensive equipment from damage and extend their operational lifespan.
Why the Relationship between pH and Conductivity Matters
Really knowing your process’s unique pH and conductivity values ensures system efficiency, prevents equipment damage from corrosion or scaling, and maintains regulatory compliance. Understanding the relationship between both parameters aids in maintaining process control and treatment, product quality assurance, and equipment management.
