Use this GC LOD Standard SD calculator to determine LOD for your chromatographic method using the formula LOD = 3*SD. It updates LOD and LOQ results instantly upon any changes.
GC LOD Standard SD Calculator Interface
What inputs are required ?
- Concentration of the target compound from a known standard
- Min 8 x peak areas of a target peak from the known standard runs
What the GC LOD Standard SD Calculator Outputs
- Average of the peak areas of the target peak
- Standard deviation of the peak areas of the target peak
- Detection limit (LOD)
- Ratio of known concentration versus the detection limit (LOD)
- Quantitation limit (LOQ)
