This was a challenge as levels of individual chemicals were near detection limits.

Concentrations in all other water samples were below detection limits.

Consequently it is difficult to quote a general detection limit.

Other approaches for defining the detection limit have also been developed.

Many of the metals were found to be in low concentration and below detection limits.

The method detection limit must be indicated when reporting to better understand the reported results.

The number of elements determined can cause a 10 fold change in detection limits.

The remaining elements were below the instrument’s detection limit and therefore omitted.

The detection limit for these analyses was not specified by the authors.

Detection limits will keep going down but zero cannot be measured in a chemical analysis.

This detection limit is insufficient for many types of applications.

The detection limit by current technology for this star system is a little less than the mass of the planet Jupiter.

In both cases, levels of amino acids were very low close to the detection limit.

"Both the detection limits and the biodiversity found are encouraging," the authors wrote.
