    Abstract: By connecting the Bradbury-Nielson gate (BNG) directly to a driver without a transmission line, distortion of the voltage waveform experienced a the BNG are much reduced. Because the magnitude of the modulation defects grows as the applied modulation voltage is increased, Bradbury-Nielson gates with finer wire spacing such as 100 microns, and operating at 10 to 15 V, significantly better signal-to-noise ratios are achieved. HT-TOFMS data were also post processed using an exact knowledge of the modulation defects.

    Abstract: A method that comprises providing a polymerized sol-gel material (PSG) and linking an enzyme to a surface of the PSG via covalent linkage is provided. The surface of the PSG is derivatized with a linker that comprises a functional group for linking itself to the surface of the PSG and a functional group for linking itself with the enzyme. The linked-enzyme PSG, or microreactor, is an effective means of at least partially digesting a substrate, such as a biological substrate. The activity of the enzyme of the microreactor may be significantly enhanced, up to 200-fold to over 2000-fold, for example, relative to the activity of the enzyme free of the microreactor. The microreactor is thus an effective vehicle for digesting a substrate such as a biomolecule, a protein, an oligonucleotide, a peptide, a steroid, and/or an organic acid, after which, any remaining substrate and one or more digestion product(s) may be separated and detected. Microreactors and integrated devices that incorporate microreactors, such as chips, columns, pipet tips, wells, and well-plates, are also provided.

    Abstract: A beam modulation device gate is constructed from a silicon material, such as a silicon layer on an silicon on insulator wafer. The device further comprises a set of electrical contacts on the layer. The layer defines a set of electrically conducting silicon material fingers forming an array, wherein each of at least some of the fingers is connected electrically to one of the electrical contacts. The gate may be used in a mass or ion mobility spectrometer. Where the gate is constructed from a silicon on insulator wafer, an insulator layer supports the silicon layer and a handle layer supports the insulator layer. When predetermined electrical potentials are applied to the electrical contacts, at least some of the fingers will be substantially at said predetermined electrical potentials to modulate a beam of charged particles that passes through said array of fingers. A plurality of devices of the type above may be used, where each of the devices modulates the beam so that the beam is deflected along a direction different from direction along which the beam is deflected by any of the remaining devices. A plurality of devices of the type above may be used for a mass gate or charged particle buncher device. For making an ion optical device, an array of fingers is formed in a silicon layer of the silicon on insulator wafer. A portion of a handle layer of the wafer on a side of an insulator layer of the wafer opposite to that of the fingers is removed; and a portion of the insulator layer is removed so that the fingers are connected to the wafer only through the silicon layer and at one end of the fingers.

    Abstract: An analog detection system for determining a ring-down rate or decay rate 1/&tgr; of an exponentially decaying ring-down beam issuing from a lifetime or ring-down cavity during a ring-down phase. Alternatively, the analog detection system determines a build-up rate of an exponentially growing beam issuing from the cavity during a ring-up phase. The analog system can be employed in continuous wave cavity ring-down spectroscopy (CW CRDS) and pulsed CRDS (P CRDS) arrangements utilizing any type of ring-down cavity including ring-cavities and linear cavities.
