Abstract:
A method for collecting particles from a source of gas and particles, the method comprising the steps of:providing a housing defining an enclosed chamber, the housing having a circular inlet opening providing fluid communication between the source of gas and particles and the chamber, and an outlet opening providing fluid communication between the chamber and the exterior of the housing, the outlet opening adapted to be connected to a fluid flow producing means for drawing gas and particles through the housing from the inlet opening to the outlet opening; providing a collecting member; coating at least a portion of the upper surface of the collecting member with an adhesive; positioning the collecting member in the chamber in the housing between the inlet opening and the outlet opening so that the distance between the inlet opening and the adhesive-coated surface of the collecting member is less than about 0.08 inches and the ratio of the distance between the inlet opening and the adhesive-coated surface of the collecting member to the diameter of the inlet opening is less than about 1; and drawing gas and particles from the source and through the housing so that the inlet opening directs the gas and particles at the adhesive-coated surface of the collecting member.
