摘要： A sol-gel poly-THF coating was developed for high-performance capillary microextraction to facilitate ultra-trace analysis of polar and nonpolar organic compounds. Parts per quadrillion level detection limits were achieved using Poly-THF coated microextraction capillaries in conjunction with GC-FID. Sol-gel Poly-THF coatings showed extraordinarily high sorption efficiency for both polar and nonpolar compounds, and proved to be highly effective in providing simultaneous extraction of nonpolar, moderately polar, and highly polar analytes from aqueous media. Sol-gel poly-THF coated microextraction capillaries showed excellent thermal and solvent stability, making them very suitable for hyphenation with both gas-phase and liquid-phase separation techniques, including GC, HPLC, and CEC. In CME-HPLC and CME-CEC hyphenations, sol-gel poly-THF coated microextraction capillaries have the potential to provide new levels of detection sensitivity in liquid-phase trace analysis, and to extend the analytical scope of CME to thermally labile-, high molecular weight-, and other types of compounds that are not amenable to GC.

摘要： A process of programming a programmable logic device (PLD) to carry out a specified logic function. The PLD contains three levels of logic implemented as a plurality of functional blocks, each with AND and OR planes, and a programmable interconnect matrix or logic expander carrying out AND logic. After providing such a PLD with specified size constraints and after specifying a logic function, the function is split or factored into subfunctions or factors. A Boolean factorization procedure chooses factors by replacing pairs of product terms in the first factor with their supercube and minimizing the number input terms and product terms required. Subfunctions or factors which are too large can be simplified by combining pairs of inputs in the interconnect matrix. The product terms of a subfunction or factor can be ordered according to the number of input terms they have and assigned to the functional blocks one at a time. Functional blocks which use many inputs or product terms per output can have some of their assigned subfunctions split so as to pack the PLD more densely. Split subfunctions or factors are recombined in the interconnect matrix. After assigning terms to functional blocks and the matrix, they are loaded into the PLD using a device programmer to configure the logic arrays in the PLD.

摘要： The subject invention concerns zirconia-based hybrid organic-inorganic sol-gel coating for optional use as a stationary phase in capillary microextraction (CME), gas chromatographic (GC), high performance liquid chromatography (HPLC), capillary electrophoresis (CE), capillary electrochromatography (CEC) and related analytical techniques. Sol-gel chemistry is employed to chemically bind a hydroxy-terminated silicone polymer (polydimethyldiphenylsiloxane, PDMDPS) to a sol-gel zirconia network. In one embodiment, a fused silica capillary is filled with a properly designed sol solution to allow for the sol-gel reactions to take place within the capillary. In the course of this process, a layer of the evolving hybrid organic-inorganic sol-gel polymer becomes chemically bonded to the silanol groups on the inner capillary walls. The unbonded part of the sol solution is expelled from the capillary under helium pressure, leaving behind a chemically bonded sol-gel zirconia —PDMDPS coating on the inner walls of the capillary. Polycyclic aromatic hydrocarbons, ketones, and aldehydes are efficiently extracted and preconcentrated from dilute aqueous samples followed by GC separation of the extracted analytes.
