What is the difference between sensitivity and detection limit?
Sensitivity is the magnitude of the response per unit concentration. Detection limit is the concentration of analyte that
produces a signal equal three times the noise level.For example if a sensor gives a response of 1500 pA for 10 nM of NO
and the noise level is 4 pA then 1500/10 = 150 pA/nM ( the sensitivity ).Three times the noise level is 3x4=12 pA.The
detection limit is 12/150= 0.08 nM.
