Chapter 1 PREFACE
Description of Validation Parameters
Accuracy Closeness of agreement between the value obtained by the method and the true value.
Precision Expresses the closeness of agreement between a series of
measurements obtained from multiple sampling. Precision is often
expressed as the standard deviation or Relative standard deviation of replicate measurements (later on RSD). Note that a method can be precise, but not accurate (so all your measurements may be close together, but the result is wrong).
Specificity The ability to measure the analyte in the presence ponents which we expect to be present in the sample matrix. So if you are determining the concentration of Iron and Chromium in water by UV/Vis spectroscopy, if there are small amounts of Fluoride and Chloride in the sample, will that affect your measurement?
Detection Limit The lowest amount of analyte in a sample that can be detected, but not necessarily quantitated. Usually the lowest limit is evaluated as the Signal-to-Noise ratio that is equivalent to 3 times the standard deviation of the no
