Detection limit
A method-dependent level associated with the ability to distinguish an analyte from background or analytical noise.
Why it matters
A nondetect does not mean absolute absence. Detection and reporting limits, units, and qualifiers must be understood before comparing results with screening criteria.
In practice
A project example
An analytical limit above the relevant screening level leaves the intended comparison unresolved.
