BGI 400 Personal Sampling Pump
Quiet 24 Hour Sampling

There are a growing number of specialist sampling applications which require flows in the 4 Lpm range for 24 hours. This need is now met by the BGI 400 Personal Sampling Pump. Designed for Indoor Air Quality (IAQ) work, the pump noise level is less than 50 dBA. Collector pressure drops of up to 40 cm of H2O can be maintained throughout the sampling period.

Applications

• 24 Hour Exposure Monitoring
• Personal Sampling as Mandated by Statute
• Powering Respirable, Thoracic, Inhalable and (PM)2.5 Samplers

OMNI-400 Personal Sampling Pump
Quiet High Flow 24 Hour Sampling

In the intervening years since BGI created the market for high flow rate 24 hour personal sampling the requirements of the scientific community have matured. BGI’s leadership position in the realm of quiet samplers coupled with strictly limited pulsation has never been challenged. The Omni name refers to the operating system which is also the name of this entire line of Pumps

Applications

• 24 Hour Personal/Area Monitoring
• Powering Size Selective Samplers Cascade Impactors
  • Respirable Samplers 4um cut
  • Thoracic/PM10 Sampler - 10um cut
  • Environmental Samplers PM 2.5 cut
  • Inhalable Samplers

Clean Lens Adapters (LFD1 and LFD2)

Aerosol Photometers have continued to grow in application and utility, particularly in the last decade. With their increasing application to ambient environmental monitoring and Homeland Defense applications, minimal maintenance has become of paramount importance. The obvious principle of blowing air over the lenses does not work. Sufficient air to keep the lens truly clean amounts to an air flow rate equal to the main flow through the instrument. This in turn leads to erroneous readings which will vary with concentration and aerosol properties.

Applications

• Active air flow through the Microdust Pro
• Long period concentration measurements
• Toxicology monitoring applications
• Homeland Defense monitoring
• Aerosol research
