Mechanisms¶
- Limit of Detection Estimation
- The discipline that guards against this is to estimate the limit in the real matrix, verify it with independent low-level samples, and carry non-detects through analysis as left-censored data
This sourceWarns against substituting numerical values for nondetects and recommends statistical methods appropriate for censored observations.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
