Wilhelm,M.; Battista,H.J.; Obendorf,D.; A versatile, sensitive, and selective high-performance liquid chromatographic (HPLC) procedure for the determination of common benzodiazepines and some of their most frequently occurring metabolites in forensic samples was developed and optimized with respect to effective and rapid sample preparation and high selectivity of the analytical assay. The optimized method includes liquid-liquid extraction of the drugs with chloroform followed by isocratic reversed- phase chromatography on a LiChrospher-100 RP-8ec column (150 x 4. [Read More]

Haidekker,A.; Huber,C.G.; Analytical 250x4.6 mm I.D. columns packed with iminodiacetic acid (IDA) derivatised silica were used to separate alkali metal ions and the ammonium ion in combination with non-suppressed conductivity detection. The addition of 2.5-10 mmol/l of the macrocyclic crown ether 18-crown-6 to the nitric acid eluent resulted in a change in the elution order and a significant improvement in the resolution between potassium and ammonium because of selective complexation of potassium.

Ross,J.; Parson,W.; Furac,I.; Kubat,M.; Holland,M.; Austrian and Croatian Caucasian population data were generated for eight tetrameric STR loci amplified in a single multiplex reaction. Fluorescent detection was employed using the ABI Prism 310 Genetic Analyzer, the 377 DNA Sequencer (ABI) and the 373A DNA Sequencer (ABI). The loci analyzed were HUMvWFA31 (vWA), HUMTH01, HUMTPOX, HUMCSF1PO, D5S818, D13S317, D7S820 and D16S539 as part of the GenePrint PowerPlex multiplex system Int J Legal Med 2001 115(1):57-60 [Read More]
