SKC Particle Size-selective Sampler Guide

With the many particle size-selective sampling devices available, it is sometimes difficult to gather all of the information needed to determine the one best suited for an application. Ultimately, it is the user's responsibility to choose the device required for a specific sampling application and environment. SKC offers several particle size-selective devices for the collection of respirable, PM2.5, PM10, or inhalable size particles. Use the convenient guide below to help select a device to meet your application and to find information on it in the appropriate page. Refer to the SKC Air Sampling Guides for specific compounds and methods.

About Particle Size-selective Sampling

The concept of size-selective sampling of industrial aerosols is based on the measurement of particles that are associated with a specific human health effect, i.e., how deeply particles penetrate into the respiratory tract. ACGIH recommends that particle-size selective threshold limit values (TLVs®) be expressed in three forms:

  1. Inhalable (100-µm 50% cut-point), hazardous when deposited anywhere in the respiratory tract

  2. Thoracic (10-µm 50% cut-point), hazardous when deposited in the lung airways and the gas exchange regions

  3. Respirable (4-µm 50% cut-point), hazardous when deposited in the gas exchange regions of the lungs

PM2.5 and PM10 sampling according to EPA regulations determines compliance with ambient air quality standards and reveals information on particle sources and their effect on the environment and public health.
