Title:

METHOD FOR TREATING SURFACE OF RELEASING CHAMBER IN CONTACT WITH TEST OBJECT

Document Type and Number:

WIPO Patent Application WO/2013/127149

Kind Code:

A1

Abstract:

Disclosed is a method for treating the surface of a releasing chamber in contact with a test object. The method comprises the following steps: (1) with regard to components made by processing stainless steel or glass, if the component is stainless steel, the stainless steel component is oxidized with an acid and then washed with an organic solvent and water, or electrolyzed after oxidation and then washed with an organic solvent and water; if the component is glass, the glass component is corroded by HCL or HF, or the surface thereof is roughened by a physical method; (2) then follows production of a deactivated layer by processing the surface of the component washed in step (1), or first production of an intermediate layer by processing the surface of the component washed in step (1), and then production of a deactivated layer by processing the surface of the intermediate layer. The method reduces the adsorption capacity of the contact surface, greatly reduces the adsorption of a test object on the inner wall of the chamber and on the surface in contact with the test object of each component, so that the tested value of the samples taken from a sampling tube is closer to the actual value of the test object in the chamber, effectively improving the testing precision of the releasing chamber.
