Air Sampler Accurately Measures Aerosols and Gases from Same Airspace
Description:

Separates and Classifies Gases and Aerosols Simultaneously to Prevent Experimental Error

This personal air sampler can analyze and classify gases and aerosols simultaneously. The accurate detection of these substances is important in biomedical, pharmaceutical, military, energy, mining, construction, environmental, nuclear, and other industries. However, when certain gases and aerosols exist in the same air space they interfere with one another during measurement, and analysis results are skewed. This sampling device developed by University of Florida researchers solves that problem by separating and collecting gases and aerosols without interference using an innovative three-chamber system.

 

Application

A three-chamber air sampling system that separates and identifies gases and aerosols sampled in the same air space

 

Advantages

  • Accurately samples gases and aerosols from the same airspace, providing a competitive advantage not available
  • Uses inexpensive components and design, providing an efficient cost-effective product
  • Three components are packaged as modules, allowing for easy installation and disassembly
  • Its light weight allows it to be carried by individuals as a personal sampler
  • Disposable cartridges avoid contamination from previous sampling



Technology

Air sampling is a critical need for many important industries. But a common situation -- gases and aerosols both present in the same airspace -- skews results for existing air-sampling technology. Because one of the prime functions of an air sampler is to give accurate readings, this poses a significant problem. University of Florida researchers have developed a technological breakthrough that addresses this issue using a three-chamber sampling device that effectively separates these substances before measurement. The first component classifies different sized aerosols and removes those that are too large to enter into the second chamber. This second chamber collects gases and the third collects finer aerosols that were not dealt with in the beginning of the process.
