• Mass Spectroscopy of Metastable Atomic Species in Gas Analysis and Processing Plasmas at High Spectrometer Source Pressures
  of this. order in the quadrupole mass spectrometer (QMS). These pressures are much closer to those of many processing plasmas so that the sampling of. neutral species, in particular, from the plasma is improved. The sampling of ion and neutral species from magnetron plasmas is a good example. The. particle...
• Flight Risk: The Threat of Criminalization
  as the result of public transit mishaps - however inadvertent - convictions are being imposed, and aviation professionals are being punished, often by serving jail time. In addition to the Brazilian manslaughter trial of air traffic controllers and the Legacy flight crew, a small sampling of high-profile cases...
• The Accurate Measurement of Biological Effective Ultraviolet Radiation
  most of the biologic effects are sensitive to the accumulated dose (as opposed to the threshold) the instrument must. provide continuous measurement or sampling rate fast enough in relation to the rate of irradiance changes. The stability is a major factor. Many observed or expected biologic effects...
• Spotlight
  The nano particle sensor from is designed for measuring filter efficiency and parti-cle contamination in ultrapure water and corrosive chemicals. It operates in either in-line or batch sampling environments. The nano monitor has four sizing channels with a starting sensitivity of 0.08, 0.1, or 0.3...
• New ASTM Method for Measuring Oil and Grease in Water and Soil
  be transported to the field for onsite measurements. In addition, hexane is not a suitable solvent for infrared analysis using transmission sampling techniques as it contains hydrocarbons. Therefore, the hexane must be removed through evaporation. If not, the hydrocarbons in the hexane will contribute...
• Assessing future trends in automated defect inspection and yield management
  , but yield levels must be raised through continuous yet discrete improvements to the process and equipment. To accomplish this, critical data have to be intelligently, quickly, and efficiently acquired and analyzed. But increasing the sampling rate and defect sensitivity of inspection systems...
• MICRO: Facilities Technologies - Adl (October 2000)
  and line shutdowns occur. This article describes two functions of Dominion's on-site chemistry laboratory. Presented first is the lab's method for sampling and measuring organic contaminants in the fab atmosphere. The article then explains how the laboratory applies a traditional wet chemical method...
• Variation and genetic control of wood density
  VARIATION AND GENETIC CONTROL OF BASIC WOOD DENSITY IN Shaw Research Centre, Sappi Forests (Pty) Ltd., P. O. Box 473, Howick, 3290, South Africa CAMCORE Cooperative. North Carolina State University, Raleigh, U.S.A. , genetic control, basic wood density, densitometry, non-destructive sampling...
• Using Portable IR Analyzer to Measure Soot Levels in Diesel Oils
  by the optical density of the medium, unless a. sampling procedure is used to limit the level of light at-. tenuated by the soot. Calibration against a laboratory. Fig.1. Mack Engine Test: demonstrating decrease in %T with. method - such as TGA - is required. soot content. IR-ATR Permits High...
• MICRO:Analysis & Metrology by Reinhold Ott p.48 (June '99)
  ). In the former case, the defects of interest are monitored, and in the latter, further analyses are based on the "smart sampling" of the defects. Because the OTF-ADC system categorizes 100% of the defects, the yield manager uses the defect segregation to determine whether further review is necessary...
