Final answer:
To accurately analyze a blood sample, a pH analyzer needs a pH meter that measures the potential across a glass electrode immersed in the solution. Calibration with standard buffer solutions is necessary for accuracy. Proper preparation and handling of the blood sample are crucial.
Step-by-step explanation:
For a pH analyzer to accurately analyze a blood sample, it needs to be equipped with a pH meter.
A pH meter is a sensitive millivolt meter that measures the potential across a thin, sensitive glass electrode immersed in the solution.
The voltage developed is directly converted into the equivalent of a pH value.
The pH meter should be calibrated with standard buffer solutions of known pH values to ensure accuracy.
The blood sample should be properly prepared and handled to prevent contamination and ensure reliable results.
