A capillary GC method is described for simultaneously measuring fentanyl and midazolam in human plasma. Plasma was extracted at basic pH with cyclohexane-isopentanol (197:3) with Ro21-2212 added as internal standard and fentanyl derivative as carrier. The drug was back-extracted in H 2 SO 4 , and th
