Dionex P680 HPLC Pump

Dionex P680 HPLC Pump

The linearity is determined over the range that is appropriate to the lowest and the highest
nominal concentration permissible in the instrument. The lowest concentration is defined
such that is similar to the determined LOQ. Determinations at 5 or more concentrations must
be made. Concentrations ranging from 25 ppb to 1ppm are typically used. A calibration plot
(peak area vs. concentration) is constructed and the equation of the calibration line and the
correlation coefficient (r) must be reported and the calibration plot is submitted. The
linearity of the plot is evaluated in terms of the correlation coefficient.
