Technical Field

The invention relates to the field of detection instruments, in particular to a titration device and a detection device for drug color contrast detection.

Background

In the field of analytical chemistry, it is often necessary to determine the substance content by comparing the shade of the colour of a coloured solution. In experiments, it is often necessary to formulate test articles with reference to a control. Preparing a solution with the same or similar color as the reference substance. When the color difference between the two is small, the solution needs to be slowly added in a small amount. Normally in drops, and at the end of the formulation, half or even a fraction of a drop may be required for additive formulation. Which is highly demanding for the operating skill of the experimenter. Less experienced experimenters often fail to formulate due to excessive addition, require reformulation, and severely impact experimental efficiency.

Disclosure of Invention
