The LDD is the lower limit at which the system can accurately calculate the concentration of an experimental sample and be sure that the concentration is higher than a blank sample. The LDD is determined by analyzing 20 blank samples, calculating the mean, and adding 3 standard deviations to this mean. Significant variation in sample concentration is expected for samples that are close to the LDD.
