In relating respiratory disorders to fine particles, there is a relationship between size and chemical composition of the particle and incidence of disease. A new type of sampler has been developed that separates and collects particles into 2 size ranges: 0-3.5 to 20 microns. Called the virtual dichotomous sampler, it is equipped with a special inlet system designed to collect 20-micron particles at 50 percent efficiency independent of wind speeds up to 20 km/hr. Description of tests performed comparing hi-volume samplers with the dichotomous samplers.
