Abstract

PURPOSE: To prepare the titled separating tube made of quartz and having high mechanical strength, by subjecting a quartz tube to chemical polishing and flame polishing, and then heating and drawing to a capillary.
CONSTITUTION: A quartz tube is dipped in an aqueous solution of hydrofluoric acid and/or an aqueous solution of a mixture of sulfuric acid and nitric acid, and the chemically polished tube is washed with water. A chlorine-containing gap or an inert gas is passed through the tube under a definite controlled pressure, and the tube is heated at ≥1,400°C with flame blasted to the surface of the rotating tube. The surface roughness is decreased to ≤0.1μm by this flame polishing. The polished quartz tube is introduced into an electrical resistance furnace having a high purity carbon ring as a heater or into a high-frequency induction heating furnace, heated, drawn, and then coated with a plastic without delay. The separating tube thus manufactured has the strength more than 2-times that of the tube manufactured by conventional process, and the endurable minimum bending radius of the tube is about 1/3 of that of the conventional tube.
