Description

Limit of detection

 S=∆I/∆C

S – sensitivity [A/M], I – current [А], С – concentration

Limit of detection

 LOD=k*σ/m

σ - standard deviation of control measurement, m – calibration curve slope, k – parameter corresponding to statistical significance, LOD [μg/ml]

Limit of quantification

 LOQ=10*σ/m

σ - standard deviation of control measurement, m – calibration curve slope, LOQ [μg/ml]
