  • Detector Tube Measurements from Pressurized Systems
    While most detector tube applications are health and safety related, many others are process related. Detector tubes are often used to monitor for combustion products in flue gases, contaminants in natural gas pipelines, ethylene levels in greenhouses or other measurements associated with process

    them. (2) Insert the detector tube into the pump's sample inlet, with the air flow arrow pointing toward the pump. (3) Line up the red dots on the pump shaft and pump end collar, and pull the pump handle all the way out. The handle automatically locks and the pump begins to draw a 100cc sample
  • Thermography Enhances the Capabilities of Laser Transmission Welding (.pdf)
    In order to investigate the weldability of plastics, a thermographic system based on an FPA detector at 7.5 to 13 µm is realized. Using this technique, the influence of different material modifications and laser irradiation parameters on the heating behavior of selected thermoplastics is analyzed
  • Critical Leak Requirements in GC/MS, LC/MS and Analytical Instruments (.pdf)
    for chromatography consists of an injection port at one end of a metal column packed with substrate material and a detector at the other end. A carrier gas propels the sample down the column while flow meters and pressure gauges in the instrument maintain a constant flow.
  • Basic Principles of Silicon Detectors
    an electron from the valence to the conduction band, is incident upon the detector, the resulting accumulation of charge leads to a flow of current in an attached circuit. Since light is not the only source of energy that can excite an electron, detectors will produce some amount of current
  • EVID3000 Used in Traffic Incident Video Detection System (.pdf)
    EVID3000 traffic incident video detector adopts full-screen multi-object detection and recognition technology to process and analyze video images received from road monitoring cameras. In this way, the product can carry out detection, alarm sounding, recording, transmission and data collection
  • PAS vs. GC for SF6 Monitoring
    Monitor vs. their own Gas Chromatograph w/ an ECD detector. NUCON injected a known quantity of SF6 into their HVAC Test System and pulled bag samples from various points. By knowing the flow rates and SF6 starting concentration, NUCON calculated the expected SF6 values at each point. The samples
  • Medical Device Link .
    In contrast, well-known lateral-flow immunoassays (LFIAs), such as pregnancy tests, do not require washing steps. In a lateral-flow test system, the antibody-antigen reaction, as well as the removal of excess reactants, takes place by chromatographic separation. The detector reagent (i.e.
  • Medical Device Link .
    or another, the focus of this article is on the microchip-based devices. Magnetic microchip detectors are tiny, inherently rugged, and very inexpensive when produced in large quantities. The magnetoresistive manufacturing technology for their volume production is well developed. These sensors
