STEVENSON UNIVERSITY in polarity. The ZB-5 column was the standard column used on the Maryland State Police GC instrument and the ZB-1 column was the experimental column. The method that is currently used on the GC for the analysis of Ecstasy at the Maryland State Police-Forensic Science Division lab is called LOW; it was altered with the ZB-1 column and named BLOW. The flow rate, ramp time, oven temperature, and hold time were individually altered for optimum separation. C. Derivatization was performed using trimethylsilylation and the method was followed according to the journal article titled, “Analysis of Benzylpiperazine-like Compounds “(Inoue, Iwata, Kanamori, Miyaguchi, & Tsujikawa, 2004). A small amount of sample was added to a micro-centrifuge tube where derivatizing agent BSTFA w/ 1% TMS, and Acetonitrile were added. The reaction tube was heated at 30°C for 30 minutes and run via GC/MS. Figure (C) represents the GC/MS chromatogram of the standard mixture underivatized. Figure (D) represents the chromatogram of the standard mixture derivatized. E.

A small amount of sample was added to the reagent and the instantaneous color reaction was observed and recorded. The reagents used were Marquis, Mandelins, Froehdes, Lafons, Dragendorff, Nitroprusside, Gold Bromide, Cobalt Thiocyanate, and Mayer’s. A. F.   H.   B. Figure (E) is a photo of the color reactions with BZP reference standard. Figure (F) is a photo of the color reaction with Ketamine reference standard. Figure (G) is a photo of the color reaction with sample 4 with the addition of Ketamine standard. Figure (H) is a photo color test results when Dragendorff reagent was added to MDMA, Methamphetamine, BZP, and Ketamine. CONCLUSION   Figure (A) represents a standard mixture run on ZB-5 column on method BLOW. Figure (B) represents a standard mixture run on BLOWCB with the ZB-1 column.   The 0.1N NaOH/chloroform extraction did reduce the abundance of caffeine present in the sample; however, it did not eliminate the cutting agent entirely. The 0.1N HCl/chloroform and acetone extractions did not produce the results desired. It was concluded that the 16
