Description

Technical Field

[0001] The utility model relates to the technical field of sample analysis, in particular to a full-automatic permanganate index analysis workstation. Background Art

[0002] Potassium permanganate index, also known as permanganate index, refers to the amount of oxidant consumed when potassium permanganate is used as an oxidant to treat water samples in acidic or alkaline media. This index is mainly used to grasp the water quality of drinking water and surface water, and is expressed in milligrams per liter (mg / L) of unit oxygen. The permanganate index is a common indicator reflecting the pollution of organic and inorganic oxidizable substances in water bodies. It is obtained by oxidizing certain organic matter and inorganic reducing substances in water samples with potassium permanganate under certain conditions, and calculating the equivalent amount of oxygen from the amount of potassium permanganate consumed. In existing permanganate index analysis workstations, multiple sample cup placement slots are usually set up, and the top of the sample cup usually extends out of the placement slot for easy removal. When the sample cup is clamped by a mechanical gripper, the surrounding sample cups may be bumped by the mechanical gripper, which may cause damage to the surrounding sample cups and affect the gripping operation of the mechanical gripper.
