APPARATUS FOR CONTROLLING AIR FLOW

摘要

PURPOSE: A flow controlling device which maintains the uniform flow rate of a sample which contacts with air is provided to be applied in a chamber which has height restriction and to filter air which contacts with a sample. CONSTITUTION: A flow controlling device comprises a specimen installation part(31), air path parts(15,16) and an air flow generating part. The specimen installation part contacts sample to some flowing air and is installed at an air flow controlling device which tests the chemical feature of a sample. The air path part has an inlet(E1) and an outlet(E2). An air channel interlinks the inlet and the outlet. The flow of air, which towards the outlet from the inlet, is created in the air flow path.
