Optionally, add 500 µl of acetate buffer and 25 µl of concentrated ß-glucuronidase. Add appropriate volume and concentration internal standards. Vortex and heat for 1-2 hours at 65 C. Allow sample to cool. Do not adjust ph- sample is ready to be added to extraction column. (Blood Sample Preparation) To 1-2 ml blood add 2 ml of 0.1M phosphate buffer (ph= 6.0). Add appropriate volume and concentration internal standards. Applying Sample to Column Load sample directly to column without any preconditioning. Pull sample through at a rate of 1-2 ml/ minute. pressure (~ 80-100 psi) for 1 minute. Wash (Blood Only) Wash sample with 2 ml of 0.1M phosphate buffer (ph=6.0+0.5). Wash (Urine and Blood) Wash sample with 1 ml of 2% glacial acetic acid/ 98 % methanol. pressure (~ 80-100 psi) for a minimum of 5 minutes. NOTE 1: (It is important to dry the column thoroughly to achieve the highest recovery of all compounds. Any residual moisture will slow down the drying of the elution solvents prior to derivatization for GC/MS analysis. Also, any residual moisture could reduce the reactivity of the derivatization agent resulting in low GC/MS sensitivity.) Elution Elute samples with ~1-2 ml dichlormethane /iso-propanol/ ammonium hydroxide (78/20/2) Evaporate fraction to complete dryness under stream of dry air or nitrogen at ~ 35 C. (Note: For amphetamine group analysis, add 200 µl of 1% HCl/ 99% MeOH to eluate to minimize amphetamine group loss to volatilization.) GC/MS Analysis Derivatize compounds with appropriate derivatizing procedure or reconstitute in 100 µl ethyl acetate and inject 1-2 µl into the GC/ MS system for analysis. LC/MS Analysis Reconstitute in methanol or appropriate mobile phase.
