WebDec 21, 2024 · Use a smaller sample size. • When measuring samples that are fairly clean, CO2 can cause the pH to change as the sample is mixed and allowed to sit and react with the air. Again this appears as drift, but it is actually the CO2 changing the pH of your sample. • Generally, plastic electrodes are not as good as glass electrodes.

This gives a range of 168.8 - 4.6 = 164.2 mV for 3.01 pH units, or 54.55 mV per pH unit. If, for example, I measure 100 mV, the pH is 100 mV / 54.55 mV = 1.83 pH units deviation from 7.01, so I subtract 1.83 from 7.01 for a pH of 5.18.
