The invention can lower the detection limits of testing chemical substance without using organic solvents.

Abstract: A dry testing method for glove (10) made with an air permeable, waterproof material (16). The stem (22) of a tee fitting (24) is connected to an air pump (20) source. A mouth (30) of the glove is tightly attached to one end (32) of the fitting so no air can escape through the mouth.
