Geologic sample
the calibration or linear range, the sample is re-analyzed after appropriate dilution. The analyst will use the least dilution necessary to bring the analyte within range. In both cases, a loss of sensitivity is experienced. All sample dilutions result in an increase in the lower reporting limit by a factor equal to the dilution.
