  • 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.
  • 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.

    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
  • Air Emissions from the Automobile Manufacturing Industry: A Bio-Oxidation Pilot Study of Paint Emissions Control
    were made to airflow (adjusting residence time) and sump water recirculation spray (biotrickling filter flow rate and biomatrix chamber timing) while monitoring the VOC inlet and outlet concentrations using a gas chromatograph equipped with a flame ionization detector (FID - Method 25A).
  • MICRO: Product Technology News (February 2001)
    , suppressor module, and conductivity detector in one compact unit. Each IC has a flow path that is constructed of PEEK. The pump provides variable flow levels from 0.2 to 2.5 mL/min, while the detector has selectable thermostat temperatures from 25 to 45 C in 5 C steps. Peripherals are kept
  • Finding the needle in a haystack
    their clothing to shake loose particles. The air and particles flow through a slot at the bottom where a metal mesh sifts out particles. The mesh is rapidly heated, sending particles into a mass-spectrometer's detector. Two to three seconds later, analysis complete, the portal flashes a green

    , or cannot characterize very high molecular weight aggregates. Figure 2. The PD2000/DLS detector combines static and dynamic light-scattering technologies in a single detector that can be coupled to any SEC/FLPC currently in the lab. A new method has very high sensitivity and can operate both in flow
