Figure Lengend Snippet: Summary of Results Obtained from 293 Real Hair Samples

Article Snippet: Reagents and standards Reagents and standards for furanyl fentanyl and 4-ANPP were produced by Chiron (Trondheim, Norway); reagents and standards for acetyl fentanyl, remifentanil and carfentanil were produced by Toronto Research Chemicals (North York, Canada); and reagents and standards for tramadol, oxycodone, hydrocodone and norfentanyl were purchased from Sigma-Aldrich (Milan, Italy).

Techniques:

LC-MS/MS ion chromatogram of a high calibrator. Each peak represents the quantitative transition ion (qualitative transition ion not shown). Fentanyl analogue and internal standard peak identities: (1) norfentanyl- d 5 , (2) norfentanyl, (3) furanyl norfentanyl, (4) remifentanil acid, (5) butyryl norfentanyl, (6) remifentanil, (7) acetyl fentanyl, (8) acetyl fentanyl- 13 C 6 , (9) alfentanil, (10) U-47700, (11) acetyl fentanyl 4-methylphenethyl, (12) acrylfentanyl, (13) fentanyl, (14) AH-7921, (15) fentanyl- d 5 , (16) 4-ANPP, (17) para -methoxyfentanyl, (18) furanyl fentanyl, (19) despropionyl para -fluorofentanyl, (20) (±)- cis -3-methyl fentanyl, (21) butyryl/isobutyryl fentanyl, (22) carfentanil, (23) para -fluorobutyryl/ para -fluoroisobutyryl fentanyl, (24) sufentanil, and (25) valeryl fentanyl. Separation between butyryl/isobutyryl and para -fluoroisobutyryl fentanyl/ para -fluorobutyryl fentanyl was not achieved due to isomerism.
