TRIS buffers, which are often present in biological samples, can cause challenges in pH measurement. Selection of the appropriate reference system can allow improved pH sensor accuracy and extended lifetime.
pH Measurement Basics
TRIS buffers, which are often present in biological samples, can cause challenges in pH measurement. The interaction between classic silver-silver chloride electrolyte solutions and the key components of the TRIS base leads to junction blockage and shortened pH sensor lifespan. Selection of the appropriate reference system can allow improved pH sensor accuracy and extended lifetime.
