FAQ

Why should pH buffer, standard and electrolyte solutions be used?

Accurate solutions are the foundation of good measurement results. High quality solutions should always be used for sensor calibration and maintenance. We guarantee maximum traceability by providing individual test certificates for every solution. Our expansive offering will ensure measurement precision and compliance in regulated industries while increasing uptime by extending the life of your sensors. Find the proper solutions for determination of pH, conductivity, ion concentration, ORP and dissolved oxygen.

How can I optimize the use of my pH buffer, standard and electrolyte solutions?

The quality of a solution is only guaranteed for unopened bottles that have not yet expired.

The following tips will help optimize the use of pH buffer, standard and electrolytes solutions after opening and while in use in the laboratory. Fresh calibration solutions minimize the measurement uncertainty and thus optimize the reproducibility of results:

  • Note the date on the bottle when the pH buffer, standard and electrolyte solutions are opened for the first time.
  • Keep the bottles sealed tightly at all times
  • Never pour dispensed pH buffer, standard and electrolyte solution back into the original bottle.
  • Ensure that bottles containing calibration solution are not contaminated.
  • Replace pH buffer, standard and electrolyte solutions that have reached the expiry date or may be contaminated.

Where can a certificate or a material safety data sheet for solutions be obtained?

The certificates of all calibration solutions and many electrolytes can be downloaded at www.mt.com/buffer. The respective material safety datasheets are available at www.mt.com/msds.

What is reference electrolyte?

The reference electrolyte ensures a stable signal transmition. It closes the electric loop by. Due to its high ion concentration, the reference electrolyte conducts the electronic signal from the reference element (mainly Ag/AgCl) to the measured medium and thus closes the electronic circuit of the pH measurement system.

How should I clean my pH sensor?

Your pH sensor should be cleaned regularly. Reduced slope and/or offset or slow response time are an indication that your sensor needs cleaning. Fats, oils, and grease should be cleaned with a non-ionic surfactant solution or methanol. Proteins should be cleaned with a Pepsin-HCl cleaner solution. After cleaning, rinse the electrode with deionized water, recondition it in 3 mol/L KCl and then store in the InLab® Storage solution.

What calibration points should I use?

Calibration should cover the range of the desired measurement values. The most common pH sensor calibration method is two-point calibration.

What should I store my sensor in?

pH glass sensors need to be kept moist at all times. If an electrode dries out during storage, a regeneration procedure is required to restore the hydrated glass layer and the reference junction in order to make the sensor operable. As a general rule, store your pH sensor in the same solution as the reference electrolyte of the sensor. In most cases this is a 3 mol/l KCl solution. Sensors with a bridge electrolyte should be stored in the electrolyte of the outer electrolyte compartment.
