• Nickel Metal Hydride Batteries; It's About Time
  Every industrial hygienist at one time or another has felt the bite of nickel-cadmium batteries. Certainly the venerable NiCad power source has served us well in every king of industrial hygiene instrument from personal monitoring pumps to multi-gas monitors. They are lightweight, reusable...
• MICRO: Critical Materials Delivery
  ) shield plate, which, under low power, enables low-level (parts-per-billion and sub-parts-per-billion) analysis of potassium, calcium, and iron without forcing users to resort to alternative analytical methods. With the exception of zinc, barium, and cadmium, elements were analyzed under low RF power...

  , and all may be detected using SPME technology. In addition to detecting the presence of well-known pollutants, the SPME system can be used to detect the presence of metal ions. Thus it could detect the presence of such things as lead or cadmium in the environment. Pawliszyn is interested in further...
• Electroplating: Solution Concentration Monitoring and Control
  , Nickel, Chromium, Cadmium, and Cobalt. It is also excellent for monitoring total solids. By installing optek sensors in strategic locations in the process, the electroplater can greatly improve batch to batch quality, reduce the number of reject parts, improve chemical and effluent management...
• Field-testing For Environmental Pollutants Using Briefcase Sized Portable LIBS System
  (Pb), Cadmium (Cd),. Nickel (Ni), Arsenic (As),. Beryllium (Be), Mercury (Hg),. Chromium (Cr), Nickel (Ni) and. Antimony (Sb) can lead to long-. term health consequences, for. these elements have exhibited a. propensity to accumulate in the. human body, causing irreversible. damage. Unfortunately...
• Don't get locked out of Europe
  be certified as not exceeding specific levels of six substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl (PBB), and polybrominated diphenyl ether (PBDE). Even companies that don't have these substances in their products must have their products certified as being free of them...
• Using the TC1142 for Biasing a GaAs Power Amplifier
  Cadmium (NiCd), or a multi-cell Nickel Metal Hydride. will provide more-than-adequate regulation for most portable appli-. (NiMH) battery pack. Figure 2 shows a simple block diagram of the. cations. Table 1 shows the relationship between output voltage. TC1142 Inductorless Boost/Buck regulator...

  case to fit in the hand or on the belt. The instrument's battery powers a small, attachable sampling pump, and the user can choose from 20 different sensors. The monitor operates on alkaline, nickel-cadmium, or NiMH batteries. A datalogging function enables users to customize the monitoring program...
• Treating wastewater from CMP using ultrafiltration
  an additive in the CMP slurries, while the high silicon level is attributable to soluble silica. Use of a colorimetric technique (the heteropoly blue method) confirmed that soluble silica levels were <4 ppm. Metal Ion Level Aluminum<10 ppb Arsenic<10 ppb Barium<10 ppb Boron72 ppb Cadmium<10 ppb...

  windows and liquid nitrogen cooled mercury cadmium telluride detector. Full spectra collected every 30 seconds provided continuous, real-time information about the nature and concentration of species of interest. Figure 2: Schematic of analytical setup and sampling system. Accurate quantitative...
