1. Describe the difference between a) accuracy and precision and b) method detection limits and practical quantitation limit. a) Accuracy is the agreement between the measured and the real value while precision is a measure of the agreement among repeated measurements taken from the same sample and under the same experimental/testing conditions. b) The method detection limit is “the minimum concentration that can be measured and reported with 99% confidence that the analyte concentration is greater than 0 while the quantitation limit is the lowest concentration that can be reliably achieved within specified limits of precision and accuracy during routine operating conditions. Thus detection limit is the ideal minimum measurable concentration while the practical quantitation limit is the lowest concentration that can be achieved reliably determined given that under most real conditions the error is larger than 1%. 2.
