Összefoglaló	The standard addition method is a quantitative analytical technique that determines the concentration of an unknown analyte by measuring the response before and after adding a known quantity of the analyte (a standard) to the sample itself. This approach compensates for matrix effects and interference from other sample components, making it invaluable when analyzing complex matrices (biological fluids, environmental samples, geological materials) where the sample composition profoundly affects the measured signal. The standard addition method is widely recognized in analytical chemistry as a primary quantification strategy when external calibration is compromised by matrix variability.	Potentiometric titration is an electrochemical method of analysis that measures the potential difference between a reference electrode and an indicator electrode as a titrant is gradually added to a solution. Developed in the early 20th century, it allows precise determination of the concentration of analytes without requiring visual endpoint indicators. This method is fundamental in analytical chemistry for determining acids, bases, redox species, and metal ions.
