It has an extreme corrosion resistance at acidic and alkaline media and does not form any intercalation compounds.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplication note\u003c\/strong\u003e\u003cbr\u003eTypically, a thin film of studied material is deposited on the glassy carbon surface. Special attention should be paid to provide a proper adhesion between the studied material and substrate. Surface pretreatment such as polishing, vacuum heat treatment, laser activation or electrochemical activation may be applied to improve adhesion. After use, the substrate can be chemically cleaned and mechanically polished using micro-sized abrasives (\u003cem\u003ee.g.\u003c\/em\u003e using sub-micron alumina powder) followed by sonication.
