▎ 摘　　要

NOVELTY - The device has a base (1) installed on a carbon-sulfur analyzer main body (2). A bottom end of a detecting platform (4) is fixed on a middle part of the carbon-sulfur analyzer main body. An operation cover (3) is installed on the carbon-sulfur analyzer main body and located on the detecting platform. A front side of the operation cover is fixed with a plate that is formed with a spiral female buckle. An upper end surface of the operation cover is fixed with a door plate through a hinge. A plywood is formed with a spiral buckle. Sides of the operation cover are fixed with an arm operation inlet that is located at a side of an elbow guard. The elbow guard is fixed with a glove. USE - Graphene material purity testing device. ADVANTAGE - The device is simple to operate and convenient to use, and has better operability, and can prevent external interference so as to improve detecting precision of graphene material purity. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a graphene material purity testing device. Base (1) Carbon-sulfur analyzer main body (2) Operation cover (3) Detecting platform (4)
