High flow impact sampler

BGI900LPM high flow impact sampler
BGI900LPM High Volume Cascade Impactor

The BGI900LPM high flow impact sampler is designed based on the research results of P. Demokritou's group at the Harvard School of Public Health.
The BGI900LPM high flow impact sampler originated from the impact samplers developed by K.R. May from Porton, England and A.A. Andersen from Dugway, USA during World War II. With the involvement of more scientists, people have gained a better understanding and recognition of this product. In the late 1960s, Virgil Marple from the University of Minnesota brought the use of this device to its extreme. Since then, although there have been some minor modifications to the equipment, there have been no fundamental changes. Until a research group from the Harvard School of Public Health, led by Professor P. Koutrakis, achieved dominance in the field. Their research provides a solution to the long-standing problem between high flow sampling and particle impact. They used the patented foam impact surface (PUF) technology to obtain the ideal collection effect of particles in large flow sample gas. The corresponding instrument is the new generation "BGI900LPM High Flow Impact Sampler (HVCI)" produced by BGI company.
This product not only meets the routine monitoring requirements of environmental air quality by agencies such as the U.S. Environmental Protection Agency (U.S. EPA), but also collects more extensive and detailed research data on the nature and chemical composition of aerosol particles, which can be used by environmentalists, epidemiologists, and global climate change experts. Ordinary large-scale routine monitoring networks can only provide limited chemical information and cannot meet the research needs of professional scholars dedicated to the formation of high-level chemical components and pathological research. BGI's 900LPM can be used in conjunction with advanced equipment to provide researchers with the necessary background information and initial data for analysis.

Purpose:
• Basic aerosol research and chemical component formation research
• Environmental monitoring in special areas
• Study of particulate matter in pathology
Research on particulate matter related to epidemics
• Radiation monitoring

characteristic:
Harvard School of Public Health Impact Design and Certification
New BGI high flow direct calibration
Professional collection medium (patented technology)
• High traffic rates that meet various analysis and detection limits

Specifications:

Calibration:
Using BGI HiVolCal makes it easy to calibrate the flow rate of BGI 900.
When connecting HiVolCal to BGI900 for calibration, a flow adapter (model - HVCI9505) is required.
