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 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
Respirable Dust Cyclones
Applications
For more than 25 years the respirable dust cyclone has been an important adjunct to personal sampling in all of the dusty trades. In many instances this type of sampling is mandated by federal regulations on a routine basis, for each employee exposed. In all dusty applications, respirable dust samplers should be utilized to guard against excessive exposure, minimizing both worker risk and potential litigation/fines.
High Flow Respirable - Thoracic Cyclones
The GK2.69 Cyclone was originally developed as dual use cyclone for both Respirable and Thoracic personal sampling applications. It has significant advantages in both size ranges. As a Thoracic sampler the GK2.69 has been adopted by NIOSH in their Manual of Analytical Methods (NMAM) as part of Standard Number 5524 for sampling airborne concentrations of Metalworking Fluids (MWF). There is no other cyclone available which fulfills the requirements of the method. A stainless steel version has been introduced (below) for any purpose but principally to satisfy the desires of Canadian clients who have a Sulfuric acid sampling requirement.
Triplex Cyclone (SCC 1.062) -- PM1, PM2.5 & Respirable
Applications
With growing interest and concern over diesel "soot", the need has arisen for a "PM1" personal sampler to investigate this fraction in the workplace. Additionally, with PM2.5 firmly established the measurement of choice for Ambient and Indoor Air Quality, there is interest in what fraction of PM2.5 may be PM1.
PM2.5 Cyclone - GK2.05 (KTL) / GK2.05SH (KTL)
Applications
While PM2.5 is a measurement mandated for ambient environmental sampling by the US EPA, there is a great deal of interest in this particular size cut. One application relates to Indoor Air Quality Testing (IAQ). There are also applications wherein forward looking investigators are interested in the PM2.5 cut in the visionary belief that it is a measurement of personal exposure significance.
H-PEM PM10 and PM2.5 Personal Impactor
The BGI H-PEM is a development of the Environmental Science and Engineering Group at the Harvard School of Public Health. It is a group of four impactors designed to be worn on the person in order to closely gage their exposure to PM2.5 or PM10 concentrations at 2 different flow rates. This results in four models. What makes this set of instruments so unique and superior to similar devices is the bold use of Silicone grease to capture the unwanted particles. The bias caused by particle bounce and the very questionable results obtained when impacting solid particles upon dry surfaces is completely eliminated.

BGI Collison Nebulizers
The Collison Nebulizer has long been the recognized technique for the efficient aerosolization of various liquids.1,2. Over the years various configurations have been developed to meet specific requirements. BGI manufactures all of the currently used types and has performed extensive tests to determine the performance characteristics.
Applications
- Aerobiology
- Aerosol Research
- Biohazard Enclosure Testing
- Filter Evaluation
NSF Collison Nebulizer
The Collison Nebulizer was first described in the scientific literature by Collison in 1935, according to May. Over the intervening years, it has become the recognized technique for atomizing liquids and suspensions. The original version had 3 jets and BGI is responsible for the standardization and publication of the 6-jet version. The National Sanitation Foundation adopted a special version of the Collison as a Standard for challenging biohazard enclosures.

STAG 2000 Monodisperse Aerosol Generator
The BGI STAG 2000 is a new design, air driven, monodisperse aerosol generator which continues the decades- long development work of our predecessors. It is also the first time an enclosure is commercially available. A detailed, illustrated, instruction manual has been prepared by a scientist and engineer completely familiar with the construction and operation of the instrument. A spreadsheet calculator has been constructed that permits all the requisite calculations to be performed governing the successful production of a monodisperse aerosol.
Applications
-
Basic Aerosol Research
-
Calibration of size selective devices
-
Dispersal of biological test aerosols
-
Pharmaceutical Aerosol test dispersals
-
Inhalation Research
