A flashlamp-pumped dye laser was modified to produce 80mJ/pulse, narrowband output at 532 nm suitable for pumping of Raman active transitions of the major combustion species CO2, H2O, N2, and O2. Simultaneous measurements of multiple species were obtained in atmospheric pressure methane-air flames, demonstrating absolutely quantitative measurements of species mole-fraction. Comparisons with Q-s...
The design, fabrication, and preliminary testing of a micromachined-Si passive vapor preconcentrator/injector (μPPI) are described. Intended for incorporation in a gas chromatographic microsystem (μGC) for analyzing organic vapor mixtures, the μPPI captures vapors from the air at a known rate by means of passive diffusion (i.e., without pumping) and then desorbs the vapor sample thermally by me...
Experimental Assessment of a Free Elastic-Piston Engine Compressor with Separated Combustion Chamber
This paper presents the experimental assessment of a free elastic-piston compressor (FEPC) equipped with a separated combustion chamber. The FEPC is a proposed device that utilizes combustion of a hydrocarbon fuel to compress air into a high-pressure supply tank, thus potentially serving as a portable power supply candidate for untethered pneumatic systems of human-scale power output. The desig...
An inexpensive, hand-held, point-of-care, disposable, self-contained immunoassay cassette comprised of air pouches for pumping, a metering chamber, reagents storage chambers, a mixer, and a lateral flow strip was designed, constructed, and tested. The assay was carried out in a consecutive flow format. The detection was facilitated with up-converting phosphor (UCP) reporter particles. The autom...
