Researchers: Deng XS, Kurosu A, Pounder DJDepartment of Forensic Medicine, University of Dundee, Royal Infirmary, Scotland. Source: J Forensic Sci 1999 Mar;44(2):343-6Summary/Abstract: Scientists in Scotland have developed a gas chromatography/mass spectrometry method for detection and quantification of anabolic steroids in head hair. anabolic steroid profiles Muscle boys. Following alkaline digestion and solid-phase extraction, the MO-TMS derivatives gave a specific fragmentation pattern with EI ionization. For stanozolol, the TMS-HFBA derivative showed several diagnostic ions. For androstanolone, mestanolone (methylandrostanolone), and oxymetholone two chromatographic peaks for cis and trans isomers of derivatives were seen. anabolic steroid profiles Steroids stacking cycles. Recoveries were 35 to 45% for androstanolone, oxymetholone, chlorotestosterone- acetate, dehydromethyltestosterone, dehydrotestosterone, fluoxymesterone, mestanolone, methyltestosterone, and nandrolone; 52% for mesterolone, trenbolone; 65% for bolasterone; 24% for methenolone and 17% for stanozolol. Limits of detection were 0. 002 to 0. 05 ng/mg and of quantitation were 0. 02 to 0. 1 ng/mg. Seven white male steroid abusers provided head hair samples (10 to 63 mg) and urine. In the hair samples, methyltestosterone was detected in two (confirmed in urine); nandrolone in two (also confirmed in urine); dehydromethyltestosterone in four (but not found in urine); and clenbuterol in one (but not in urine). Oxymethalone was found in urine in one, but not in the hair. One abuser had high levels of testosterone: 0. 15 ng/mg hair, and 1190 ng/mL urine. These researchers conclude that head hair analysis has considerable potential for the detection and monitoring of steroid abuse. Discussion: When seeking to find out what chemicals are present in a sample (e. g. , hair), you have to be able to effectively separate all the different substances it is made of. Usually this is done on the basis of differences in solubility, using fractional crystallization, or by differences in volatility, using distillation, of the different substances it contains. Chromatography is the most widely used technique used in chemistry to separate substances. It can be used on liquid or gas solutions.
