Matrix Effects
Sometimes the solution matrix in which the analyte resides affects the relationship between the signal and the analyte’s concentration, as shown below. We call this a matrix effect. When matrix effects are […]

Determinate Errors in Single-Point Standardizations
When using a single-point standardization, we must assume that there is a linear relationship between the signal and the analyte’s concentration. When this is not true, which often is the case at […]
Constant Determinate Errors
The magnitude of a constant determinate error is the same for all samples and is more significant when analyzing smaller samples. Analyzing samples of different sizes, therefore, allows us to detect a […]
