detection limit 

in analysis
https://doi.org/10.1351/goldbook.D01629
The minimum single result which, with a stated @P04855@, can be distinguished from a suitable blank value. The limit defines the point at which the analysis becomes possible and this may be different from the lower limit of the determinable analytical range.
