  • Ensuring Contamination Control in Clean Manufacturing Environments with Airborne Molecular Contamination Monitoring info@

    Abstract In clean manufacturing environments, two aspects of molecular contamination need to be understood: (1) the background levels of contamination existing under stable conditions, and (2) the elevated concentrations that occur during contamination events. A new approach to monitoring both aspects of molecular contamination is presented. Recent technical advances have ...

  • Nanoparticle Monitoring in Ultra-Clean Manufacturing Environments

    Abstract With its 10 nm sensitivity, the NPC10 NanoParticle Counter bridges the gap between conventional aerosol optical particle counting at 0.1 μm (100 nm) and sub-nm scale airborne molecular contamination. Experimental and field data demonstrate that ISO Class 1 and 2 environments, which have very low concentrations of particles greater than 100 nm, can possess much higher ...

  • New ISO draft standard classifies surface particle cleanliness

    With today’s rapid technological progress and miniaturization, clean surfaces are of growing interest and vital importance for many high-tech industries and applications.The International Organization for Standardization Technical  Committee (ISO/TC) 209 is taking steps to fill the need for global standards addressing surface contamination. Since its inception in 1993, ISO/TC 209 has ...

  • On-Line Fast Analysis of AMC from ppt to % levels in Clean Air Room

    To ensure people’s safety and a good repeatability of industrial process, near real-time risk management and the continuous monitoring are crucial. In the semiconductor fabrication process, particle control is an essential part. Clean room technology, which relies on the use of HEPA and ULPA filtration, has in the past exclusively focused on the control of micro- and nano-particles. ...

  • Air filtration applications for membranes

    Given their unique performance attributes membranes are finding use in a growing number of high efficiency air filtration applications. One example is in respirators and personal protective equipment. Applications where intense physical demands and risk of exposure to harmful contaminants are present demand the high efficiency / low pressure drop combination of expanded polytetrafluoroethylene ...

  • Sick-building syndrome and building-related illness

    Significant health problems linked to very poor indoor air qualityIndoor Air Quality (IAQ) deals with the content of interior air that could affect health and comfort of building occupants. The IAQ may be compromised by microbial contaminants (mold, bacteria), chemicals (such as carbon monoxide, radon), allergens, or any mass or energy stressor are more prevalent than anyone could have predicted. ...

  • What are we doing to our children’s brains?

    Environmental chemicals are wreaking havoc to last a lifetime The numbers are startling. According to the U.S. Centers for Disease Control and Prevention, about 1.8 million more children in the U.S. were diagnosed with developmental disabilities between 2006 and 2008 than a decade earlier. During this time, the prevalence of autism climbed nearly 300 percent, while that of ...
