Detector Sensitivity:

The sensitivity of a detector depends upon its operating principle. Sensitivity or detectability has been described as the ratio of the smallest detectable quantity measured at double the noise level to the peak width at base in seconds. For instance, a 0.1 ng (10^-10 g) sample with a 60 sec peak width at base would show a sensitivity of 1.6 × 10^-12 g/sec If the column temperature is lowered and the similar sample now has a 180 sec peak width at base (because of longer retention time) the resulting sensitivity would be 0.55 × 10^-12 g/sec.
