Temperature and pH (on the total scale—pHT) were measured every 2 days. pH probe was calibrated every week using TRIS (Tris/HCL) and AMP (2-aminopyridine/HCl) buffers (salinity 25) following best practices45. Total alkalinity (TA) was measured weekly in each aquarium from filtered water ...
It is important to use fresh pH buffers every time the meter is calibrated as the solutions need to be of known value. How do we perform a multi-point calibration? Select three pH buffers (using a range of pH’s – 4,7 and 9 is typical). The pH meter should then be put into ...
The composition of buffer solutions varies depending on the manufacturer. When selecting a buffer set, care must be taken to ensure they are made according to the formula established by the National Institute of Standards and Technology (NIST). These buffers have pH values of 4.01, 6.86, and ...
