PM2.5 Very Sharp Cut Cyclone (VSCCTM)
This cyclone was developed by BGI and Dr. Lee Kenny of the Health and Safety laboratory, Sheffield, UK. This device, called a Very Sharp Cut Cyclone is the culmination of a long series of cyclone research projects. Because of its remarkable match to the WINS penetration curve it was subjected to testing for EPA equivalency Designation.
Applications
- New Cyclone design with significant improvements over the BGI Sharp Cut Cyclone (SCC)
- U.S. EPA Federal Reference Method Designated
(RFPS-0498-116)
- PM2.5 Separator for ALL Commercial FRM Samplers
- Model VSCCA for RAASTM, PARTISOLTM& MASSTM
- Model VSCCB for BGI PQ200 & PQ200A FRM Samplers
- PM2.5 Continuous Particulate Monitor Inlet
- Indoor Air Quality Sampling Inlet
- Speciation and Air Toxics Sampling
- Laboratory Aerosol Research Separator

PM2.5 Sharp Cut Cyclone
Because of a perceived need for a non impactive - but WINS equivalent - device, the SCC was developed by BGI and tested by Dr. Lee Kenny of the Health and Safety Laboratory, Sheffield, UK. The SCC design was based upon previous, peer reviewed works. Both the WINS and the SCC were rigorously laboratory and field tested
Applications
- Ambient PM2.5 sampling
- Indoor Air Quality sampling
- Speciation sampling
- PM2.5"Type 3" sampling

PM1 Sharp Cut Cyclone
The Sharp Cut Cyclone (SCC) for EPA type PM2.5 sampling was developed and tested for non-EPA designated sampling applications wherein dry sampling is imperative (speciation) or long intervals without cleaning were essential (continuous monitoring). PM1 sampling has no official status at this time. However, there are reasons why this further development of the SCC family was carried out.
Applications
- Ambient PM1 sampling
- Indoor Air Quality sampling
- Speciation sampling
- PM1 "Type 3" sampling

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. |

GK4.162 Respirable @ 9.5 LPM
The GK 4.162 designed by BGI is the highest flow rate personal cyclone for respirable sampling. The sampler was developed under a contract supported by the National Institute for Occupational Safety and Health (NIOSH) and tested at the Health and Safety Laboratory (UK).
The design is a natural extension of the GK 2.69 Cyclone which was developed as a dual use cyclone for use in sampling Respirable and Thoracic dust fractions. It has become popular as a high flow rate Respirable sampler for Silica. At 4.2 lpm there were many investigators who nonetheless felt that this was not sufficient and something in the order of 8-10 lpm was necessary |

Custom Cyclones
Over the past decade or more, personnel at BGI have acquired extensive experience in the design and manufacturing of cyclones for the Ambient Monitoring, Industrial Hygiene, IAQ and Aerosol Science areas. At this point we are pre eminent in this technology. This is demonstrated by the fact that the USEPA and the four leading manufactures of particulate air samplers rely on our designs for their equipment. We have also designed as few as a single specimen for special needs in aerosol science and highly toxic applications. Materials of construction vary from raw aluminum to stainless steel. The variety of shapes and configurations may be appreciated by viewing our standard offerings.
