WebSensitivity is the change in the response of a measuring instrument divided by corresponding change in the stimulus or simply the gradient of the calibration function (1) (1). Sensitivity is often interpreted as related to the detection/determination ability. WebFor the ammunition used here, enhanced sensitivity was observed for the triple quadrupole configuration (LC-MS/MS), with accuracies as high as 80 %. However, under the extraction and EI-quadrupole instrumental configuration used in this study, GC–MS could not detect enough characteristic compounds to identify OGSR, especially in lower calibers.
