Simultaneous Determination of Methamphetamine and Its Isomer N-Isopropylbenzylamine in Forensic Samples by Using a Modified LC-ESI-MS/MS Method

<div>MRM chromatograms for the detection of MA and N-IBA by our routine screening procedures. (a) Upper: detected MA-Standard and the abundance ratio of MA-Standard between <i>m/z</i> 150/91and <i>m/z</i> 150/119, lower: blank. (b) Upper: detected suspect sample and the abundance ratio of suspect sample between <i>m/z</i> 150/91 and <i>m/z</i> 150/119, lower: blank.</div>
