    摘要: A mass spectrometer probe is formed of a nonconductive polymer that is doped with conductive material. The probe may be used as, or as part of, a repeller plate in a parallel laser ion desorption/ionization time-of-flight mass spectrometer. Transparent locations on the probe enable a sample placed thereon to be visualized before or during mass spectrometry. The conductive nature of the probe maintains the consistency of the electromagnetic field applied to the sample. The probe also displays low outgassing and high mechanical and chemical stability, thereby enabling it to be used repetitively.

    摘要: Polyurethane polymers bearing multiple reactive groups are readily prepared from easily accessible precursors. The reactive groups of the polymers are then derivatized with binding functionalities for analytes, energy absorbing molecules for matrix assisted laser desorption/ionization mass spectrometry, fluorescent moieties and the like. The reactive groups can also be converted to different reactive groups having a desired avidity or specificity for a selected reaction partner. The polymers are incorporated into devices of use for the analysis, capture, separation, or purification of an analyte. In an exemplary embodiment, the invention provides a substrate coated with a polymer of the invention, the substrate being adapted for use as a probe for a mass spectrometer.

    摘要: An improved electron multiplier bias network that limits the response of the multiplier when the multiplier is faced with very large input signals, but then permits the multiplier to recover quickly following the large input signal. In one aspect, this invention provides an electron multiplier, having a cathode that emits electrons in response to receiving a particle, wherein the particle is one of a charged particle, a neutral particle, or a photon; an ordered chain of dynodes wherein each dynode receives electrons from a preceding dynode and emits a larger number of electrons to be received by the next dynode in the chain, wherein the first dynode of the ordered chain of dynodes receives electrons emitted by the cathode; an anode that collects the electrons emitted by the last dynode of the ordered chain of dynodes; a biasing system that biases each dynode of the ordered chain of dynodes to a specific potential; a set of charge reservoirs, wherein each charge reservoir of the set of charge reservoirs is connected with one of the dynodes of the ordered chain of dynodes; and an isolating element placed between one of the dynodes and its corresponding charge reservoir, where the isolating element is configured to control the response of the electron multiplier when the multiplier receives a large input signal, so as to permit the multiplier to enter into and exit from saturation in a controlled and rapid manner.
