Tracking Detector Sensitivity

64
In addition to using the EMF features of the GC and detector,
also track detector sensitivity. Sensitivity reflects the
performance characteristics of a given system, and decreased
sensitivity may indicate the need for routine detector
maintenance. Sensitivity is typically reported as:
peak area
Sensitivity =
amount
Calculate a minimum detection limit (MDL) from the following
formula:
2 x noise
MDL =
sensitivity
where the noise is the ASTM noise reported by the Agilent data
system.
