• Evaluating reusable HDPE containers for delivery of high-purity hydrofluoric acid
  R. Thomas Talasek, Brian K. Hunt, and David C. Cooke, As semiconductor device geometries continue to shrink, the purity of process chemicals has become even more critical. Nowhere is this more evident than in the specifications for reducing metallic and particulate impurities, especially...
• Infrared Thermography - the Binding Link to IPD
  . thermography. The ambient conditions require internal mapping of temperature, particulate. contamination, psychrometrics (relative to absolute humidity), TVOC's, airflow/volumetric measurements,. etc., and this activity allows us to map key areas of concern for better quantification. The instruments. utilized...
• MICRO: Semicon West Technical Program (June 2002)
  for semiconductor manufacturing. There are presentations on test methods and results intended to measure corrosion resistance, contamination, and particulate generation in high-purity gas systems. STEP: 300-mm Wafer ID Mark Requirements and Challenges Chair: Winthrop Baylies, Bay Tech Group...
• Medical Device Link .
  , none states what products or processes require such an environment. A cleanroom is designed to enable manufacturers to control particulate contamination, temperature, and, where necessary, humidity. It controls the introduction, generation, and retention of particles in the room, protecting...
• A Closer Look at Form-Fill-Seal Technology
  possible, nonviable particulate matter. Filter integrity testing is needed for the filter(s) that are used to sterilize the product, and the filter(s) used to ensure the required air quality within the FFS machines. The internal air shower and container molding process is critical in sterile product...
• Containment Technologies Group
  results from a typical batch of a currently used sterile product, encompassing qualitative and quantitative chemical purity, levels of particulate matter, and results of sterility and pyrogen testing. Or they may include results of tests for particulate level, sterility, pyrogen content...
• Nickel in Society: An Understanding of Sustainable Development
  . Occupational Exposure Limits For Nickel And Nickel Compounds. #5 -- 1998 Published by the Nickel Development Institute. About this Status Report. Pending and Potential Changes to Occupational Exposure Limits. Existing Occupational Exposure Limits. ACGIH Particulate Sampling Criteria and Nickel Exposures...
• Occupational Exposure Limits For Nickel And Nickel Compounds
  Limits. ACGIH Particulate Sampling Criteria and Nickel Exposures in the Workplace. About this Status Report. The purpose of this Status Report is to bring together information on Occupational Exposure Limits, OELs, for nickel that would be of interest to occupational health personnel, workers...
• Development of A Filter Cake Permeability Test Methodology (.pdf)
  or a. particulate filter cake. It is an important characteristic that filter aid manufacturers use for. product specification, along with bulk density, particle size, solids retention, and other chemical. and physical properties. Currently in the US and Europe, there has not been a standard filter aid...
• MICRO: Product Technology News (May '2000)
  fluid temperatures to 212 F or pressures to 2500 psi. All of the sensors offer good resistance to particulate contamination in process fluids and feature solid-state design. They also have integrated electronics, eliminating the need for a separate controller. The sensors are minimally intrusive...
