Measurement of pH is done in countless different environments and sample temperature often deviates from ideal, ambient conditions.
This webinar aims to demonstrate not only the importance but also the variety of impacts of temperature on the pH value of a solution and its analysis. If temperature in pH determination is neglected, results easily become imprecise, scattered and irreproducible and thus hardly interpretable. This is the reason why simultaneous temperature measurement has become part of good laboratory practice in pH analysis.
This presentation covers not only calculative temperature compensation, but also the use of temperature tables, the design of the sensor and the use of appropriate membrane glass as suitable measures to account for temperature impact in pH measurement. The presentation addresses various ways in which temperature impacts pH measurements and discusses temperature compensation during calibration of instruments with buffers and measurement of pH in samples.
Join this webinar and get the most of your pH measuring instruments.
- Learn how temperature affects the pH of the sample as well as of the sensor
- Discover why the pH sensors and buffers/samples are major sources of error caused by temperature effects
- Understand the importance of measuring at the same temperature as during calibration
