Center: Mickey Leland National Urban Air Toxics Research Center (NUATRC)
Center Director: Beskid, Craig
Title: Development of a Personal Cascade Impactor Sampler (PCIS)
Investigators: Sioutas, Constantinos
Institution: University of Southern California
EPA Project Officer: Katz, Stacey
Project Period: October 1, 2000 through December 31, 2001

Description:

Objective:

The objective of this project is to develop a Personal Cascade Impact Sampler (PCIS) for particulate matter (PM) that will separate airborne particles by size and allow for analysis of the particles toxic metal content. The sampler will separate particles into five size fractions and will collect sufficient material for gravimetric analyses, analyses of the toxic metals inductively coupled plasma-mass spectrometry (ICP-MS), and inorganic ions by ion chromatography (IC) techniques.

Approach:

The proposed PCIS will be a miniaturized cascade impactor, consisting of four impaction stages and one after-filter stage. The sampler will operate with the help of a high efficiency personal air pump. One sampler unit will be developed as part of this grant.

Expected Results:

We expect to develop a personal sampler for PM that will allow the separation of airborne particles by size. This will improve analyses of the particles to broaden scientific understanding about the toxic metal content of PM.
