Enhancement of peroxyoxalate chemiluminescence (PO-CL) intensity by a surfactant in the H(2)O(2)/bis(2,4,6-trichlorophenyl)oxalate (TCPO)/rhodamine B system was described. The effects of 15 surfactants were evaluated by comparing the ratio of a relative CL intensity (RCI) with surfactant to that of the blank in each system. In preliminary study,(More)
A sensitive semi-micro column HPLC method with peroxyoxalate chemiluminescence (POCL) detection and column switching has been developed for simultaneous determination of 3,4-methylenedioxymethamphetamine (MDMA) and related compounds, for example 3,4-methylenedioxyamphetamine, methamphetamine, and amphetamine, in hair. After digestion of the hair with 1 mol(More)
A sensitive and selective high performance liquid chromatography-peroxyoxalate chemiluminescence (PO-CL) method has been developed for the simultaneous determination of chlorpheniramine (CPA) and monodesmethyl chlorpheniramine (MDCPA) in human serum. The method combines fluorescent labeling with 4-(4,5-diphenyl-1H-imidazole-2-yl)phenyl boronic acid using(More)
Personnel who prepare and administer chemotherapeutic agents have been reported to develop untoward effects. The use of appropriate techniques for preparing these agents is encouraged, and educational training systems that involve the use of a fluorescent or chemiluminescence reagent as placebos have been established to minimize potential exposure to these(More)
Advancements of silicon technology have led to the field of Micromachining in which it is now possible to create discrete transmitting and receiving devices on the scale of a cubic millimeter. Given such technological capabilities, it is now worth while investigating situations in which these devices can be utilized. In this paper a network of such devices(More)
This paper presents the development of hydraulic performance in a high head Francis pump-turbine runner which is adopted at pumped storage power plant. In order to achieve the improvements of turbine efficiency, pump efficiency and cavitation performance for turbine and pump mode throughout a wide operating range, a new runner was designed by the latest(More)
