Detect is the most advanced computer program for the computation
of detection and quantification limit estimates. |
| |
|
 |
Detect can compute both detection and quantification limits from
either single concentration data or calibration based data (i.e. multiple
concentrations). |
| |
|
 |
Detect can simultaneously model the relationship between true concentration
and measured concentration and the relationship between true concentration
and measurement variability using weighted least squares (WLS). |
| |
|
 |
Detect computes both the critical level (LC) and the detection
limit (LD) for each calibration based estimator. |
| |
|
 |
Detect can compute detection limits based on either prediction
limits or tolerance limits. Detection limits based on prediction
limits provide 99% confidence for the next single detection decision
whereas detection limits based on tolerance limits provide 95% confidence
of including 99% of all future detection decisions. |
