pH Buffers

In many chemical and biochemical processes, maintaining a pH range is crucial for the accuracy of output as well as operability. This is because reaction of various enzymes and chemicals depends on the pH value. A pH of 7 is neutral, below 7 is acidic, and above that is alkaline. There acidic, alkaline, as well as neutral buffer solutions, and you need to choose the right one based on your application requirement. The acidity increases with the decreasing pH value, while alkalinity increases with increasing pH value. This is where buffer solutions are required as they help maintain the required pH levels by resisting any changes due to external parameters. By and large, they maintain the stability of the pH and thus the overall process. Cannon Water provides some of the best ORP buffer solutions, pH buffer solution kits, and more. We offer our own brand of these products and also source them from other reputed and certified brands such as Myron L, HM Digital, and so on.

How pH Buffers Work

A pH buffer is actually a combination of a weak acid and its conjugate base. It can withstand pH changes when an acid or base is introduced into the solution. The balanced presence of the weak acid and its conjugate base, enables them to react with any added acid or base, maintaining the pH value.

How to Select the Right Buffer Solution for pH Calibration

When choosing a pH calibration buffer solution, there are several factors that should be taken into consideration.

  • It is advisable to choose a pH calibration solution with a known and reliable pH value. This will guarantee that calibration of the pH meter or electrode is accurate and that subsequent measurements will be reliable.
  • Consider the range of pH values being measured. Different buffer solutions have different pH values, and it is important to choose a buffer solution for pH calibration that is appropriate for the pH range being measured. It is always a good idea to choose buffer solutions that are closest to the pH range of the samples being measured.
  • Keep an eye on the shelf life and stability of the chosen buffer solution. Be informed that pH calibration buffer solutions have a limited shelf life, and their properties can change over time. It is always recommended to invest in buffer solutions with longer shelf life and stability to minimize the need for frequent recalibration.
  • Check the compatibility of the buffer solution with the sample being tested. Some samples may have specific requirements, and it is crucial to select a buffer solution that is compatible with the sample to ensure accurate and reliable measurements.
  • Invest in pH buffer solutions that are accurately and properly labelled and certified. The solutions that are traceable to recognized international standards, like NIST give assurance of their accuracy.

How to Store Buffer Solution for pH Calibration

To maintain optimum stability and effectiveness, buffer solutions should be stored properly. As improper storage leads to inaccurate results and potential experiment failure, the solution must be stored following the guidelines as listed below.

  • Store buffer solutions at the appropriate temperature, usually within the range recommended by the manufacturer. Storing them under extreme temperatures can change the pH and chemical composition of buffer solutions, making them ineffective.
  • Ensure that they are stored in air-tight containers - such as glass bottles or plastic containers made from high-density polyethylene (HDPE) - to prevent evaporation and contamination.
  • Implement a first-in, first-out (FIFO) system for buffer solution storage. This practice ensures that older solutions are used before newer ones.
  • Buffers, like any other chemical, should be stored following all appropriate safety protocols. This includes keeping buffer solutions away from food or drink storage areas, along with keeping them away from access by unauthorized individuals.
  • It is highly recommended to label each container with the buffer solution name, concentration, pH, and date of preparation or expiration. Doing so will guarantee accurate identification and proper rotation of buffer solutions. This significantly minimize the risk of using expired or incorrect solutions.
  • Allocate a dedicated storage area for buffer solutions, preferably away from direct sunlight, heat sources, and volatile chemicals. The area designated for buffer solution for pH calibration should also be well-ventilated and free from potential contaminating agents.

pH Buffer Solutions FAQ:

  • How do pH buffers work?

pH buffers work by maintaining a stable pH value despite additions of acid or base. They contain a weak acid and its conjugate base (or a weak base and its conjugate acid) that resist changes in pH when small amounts of acid or base are added. This allows users to calibrate or adjust the pH of a solution being measured.

  • Why is calibration with pH buffers important?

Calibration with pH buffers is crucial to ensure accurate pH measurements. Over time, pH electrodes and instruments may drift from their original calibration, leading to inaccurate readings. By calibrating pH buffers of known pH values, the accuracy of pH measurements can be verified and adjusted if necessary.

  • How are pH buffers used for calibration?

To calibrate pH instruments, the user typically prepares a set of two or more pH buffers with known pH values. The instrument is then calibrated by measuring the pH of each buffer solution and adjusting the instrument's readings to match known pH values. This establishes a reliable reference for subsequent pH measurements.
