Near Real-time, Low-cost, Hand-held Sensors for Measuring Elemental Concentration of Airborne Particles for Indoor or Outdoor Air Quality Monitoring

Airborne particles can have great impact on air quality, weather, and human health. In particular, long-term inhalation of toxic particulate matter in workplaces could pose a significant health risk. NIOSH scientists have developed a new, low-cost approach based on application of atmospheric radio frequency glow discharge (rf-GD) optical emission spectroscopy...

Focused Electrostatic Collection of Aerosol Particles for Chemical Analysis by Spectroscopic Techniques

This CDC-developed technology is an aerosol preconcentration unit (APU) designed for use with spectroscopic detection techniques, including emission, Raman, or infrared spectroscopies. Most existing pulsed microplasma techniques, such as laser-induced breakdown, for aerosols rely mainly on filter-based collection and suffer from poor accuracy, precision,...

Use of Detector Response Curves to Optimize Settings for Mass Spectrometry

This CDC developed optimization technology allows one to characterize the behavior of the coefficient of variation (CV) for a range of mass spectrometer machine settings. Surface-enhanced laser desorption/ionization (SELDI) and matrix-assisted laser desorption/ionization (MALDI) are used for the early detection of numerous diseases, for example cervical...
