Detection capability

Detection capability describes the performance of a measurement system at small measured quantity values.

• Limit of blank (LoB)
  Limit of blank (also known as the critical value) is the highest quantity value that is likely to be observed, with a stated probability, for a blank material.
• Limit of detection (LoD)
  Limit of detection (also known as the minimum detectable value) is the quantity value, for which the probability of falsely claiming the absence of a measurand in a material is beta, given probability (alpha) of falsely claiming its presence.
• Limit of quantitation (LoQ)
  Limit of quantitation is the smallest quantity value that meets the requirements for intended use.
