Bodily fluid is analyzed for the presence of drugs of a selected panel of drugs in a simultaneous assay in which sample of the fluid is incubated with additional amounts of all drugs of the panel, antibodies specific to each of the drugs of the panel, and microparticles, the microparticles being divided into subsets, one subset for each drug in the panel and each subset distinguishable from the others. The incubation is performed in a liquid medium in which competitive binding occurs, the drugs in the sample competing with those added to the assay medium for binding to the antibodies. In one procedure, the added drugs are pre-coupled to the microparticles while the antibodies are not, and the incubation is followed by further incubating the microparticles with labeled ligands that have affinity for the antibodies. In an alternative procedure, the added drugs are not coupled to the microparticles but are pre-labeled, while the antibodies are pre-coupled to the microparticles, and the assay proceeds without further incubation. In both alternatives, the microparticles are ultimately recovered from the assay medium and from any unbound species, and the recovered microparticles are analyzed by flow cytometry to obtain indications of the presence of the various drugs in the sample in an inverse manner by detection of the label, each drug differentiable from the others by the distinguishing features of the microparticles.

A microchannel device includes several mass transfer microchannels to receive a fluid media for processing at least one heat transfer microchannel in fluid communication with a heat transfer fluid defined by a thermally conductive wall, and at several thermally conductive fins each connected to the wall and extending therefrom to separate the mass transfer microchannels from one another. In one form, the device may optionally include another heat transfer microchannel and corresponding wall that is positioned opposite the first wall and has the fins and the mass transfer microchannels extending therebetween.
摘要:
Biological samples are analyzed for benzodiazepines in a single isocratic analysis using a chromatographic column system containing an immobilized enzyme reactor which cleaves glucuronic acid-conjugated benzodiazepines, an anion exchange column, a hydrophobic cation exchange column and a reverse-phase analytical column. Preferred methods of performing the analysis further involve the use of a hydrophobic cation exchange precolumn prior to the anion exchange column. The system readily lends itself to automation, automatic periodic sampling and benzodiazepine identification and quantification. The system is particularly well adapted to the determination and identification of benzodiazepines in urine samples.

A multi-faceted, rotatable promotional display device for being retained relative to a vehicle for enabling the perception of multiple promotional messages from a single vantage point. A display casing with multiple display surfaces is rotatably retained relative to a base structure. Promotional messages are displayed relative to the display surfaces, and a drive arrangement rotates the display casing relative. The display casing can have a square, triangular, or other cross section. The base structure can have a cup portion with a raised peripheral ridge, and a shell can envelope the display casing. The display surfaces can be electronic display screens or light transmissive panels. A light source can be disposed within the display casing. A drive motor can be powered by a battery, a photovoltaic array, or a wind turbine. A clutch or a force sensor can prevent the application of excessive rotational force.
