•A standard (a.k.a. control) is a sample with known conc. of analyte which is otherwise similar to composition of unknown samples.
•A blank is one type of a standard without the analyte.
•A calibration curve - a plot of signal vs conc. for a set of standards.
•The linear part of the plot is the dynamic range.lin
•Linear regression (method of least squares) is used to find the best straight line through experimental data points.
