The standard addition method solves this by spiking the sample with known analyte concentrations, ensuring that the response is influenced only by the analyte itself. This technique compensates for interferences, improves measurement accuracy, and is widely used in pharmaceutical, environmental, and food safety testing. In our latest article, we explore how this method works and why it remains a gold standard in chemical analysis."}
