How to spike a sample with standard
WebStandard addition involves adding known amounts of analyte to an unknown sample, a process known as spiking. By increasing the number of spikes, the analyst can extrapolate for the analyte concentration in the unknown that has not been spiked. [2] There are multiple approaches to the standard addition. The following section summarize each approach.
