I. Overview 

The coal carbonate carbon dioxide analyzer complies with the national standard GB/T 218-2016 "Determination of Carbonate Carbon Dioxide Content in Coal" and is a device for measuring the carbonate carbon dioxide content in coal. The determination of carbon dioxide employs the alkali asbestos absorption gravimetric method. The working principle of this device is that a quantitative coal sample reacts with xys, and the carbonate in the coal sample decomposes to release carbon dioxide, which is absorbed by a U-shaped tube filled with alkali asbestos. The carbonate carbon dioxide content in the coal is calculated based on the mass increase of the U-shaped tube. This device features an aesthetically pleasing and rational structure, convenient operation, and high precision and accuracy in measurement results.
