We compared a stabilized-temperature L'vov platform furnace containing an end-heated graphite atomizer (HGA) and transverse Zeeman background-correction system with a side-heated furnace system (transversely heated graphite atomizer; THGA) containing a longitudinal Zeeman background-correction system for the determination of aluminum in plasma and urine. The regression statistics for the correl...

PURPOSE The purpose of this investigation was to compare the pharmacokinetics of midazolam following intravenous, intranasal drop, and nasal-atomizer administration in beagle dogs. METHODS Six animals weighing 9-13 kg were used in a repeated-measure design, group assignment based on route of drug administration. Midazolam (1.5 mg/kg) was administered with the delivery route based on group ass...

A widely distributed spray is an important feature for atomizer which required in various applications such as gas cooling, turbine combustion, and fluidized bed granulator. Pressure-swirl example of provides a wide angle through the swirling effect inside atomizer. One parameters affecting geometrical constant, K. Another parameter pressure-swirl discharge coefficient, Cd. Discharge coefficien...

Abstract Metallic powders for additive manufacturing (AM) processes are primarily produced by gas atomization, which consists of three steps: melting, atomization and cooling. In the present work, we report on refurbishing a laboratory-scale atomizer. The equipment facilitates small-scale useful developing tailored specifically to metal AM (e.g. binder jetting, laser powder-bed fusion direct en...

rotary atomizers are commonly used in spray dryers to atomize feed. one destructive effect of wheel rotation is the creation of a vacuum inside the wheel that conducts hot air from the chamber into the wheel and can lead to atomizer blockage and an explosion. the present work determined the air-pumping characteristics of a rotary atomizer with a 50 mm wheel diameter. the vacuum pressure and pow...

AbstractThe atomization mechanism of the gas-liquid multiphase flow through an internally mixing twin-fluid Y-jet atomizer has been studied by examining both internal and external patterns...

A method is described for direct analysis of lead in blood utilizing the carbon rod atomizer. Aliquots of whole blood are analyzed without pre-treatment. Resuits are comparable to those for a similar non-flame technique in which whole blood samples were prediluted with “Triton X-100.” The small sample volumes required and the minimal sample preparation further diminish the possibility of spurio...

Pressure swirl atomizers are widely used in gas turbine combustor; this paper is aimed at researching the effect of low ambient pressure (0.1 MPa to 0.01 MPa, lower than an atmosphere) on spray cone angle atomizer. The captured by high-speed photography; then, image post program process magnitude. A mathematical model a single droplet’s movement and trajectory based force analysis proposed vali...

In graphite furnace atomic absorption spectrometry (GF-AAS), the atomization process of lead occurring in graphite atomizers with/without a platform plate was investigated when palladium was added to an iron-matrix sample solution containing trace amounts of lead. Absorption profiles of a lead line were measured at various compositions of iron and palladium. Variations in the gas temperature we...
