A reasonable and practical analysis process was selected and designed. The organic combination of pyrolysis analysis and residual carbon analysis was fully utilized, and the reasonable coordination of nine way valves, two position five way solenoid valves, and six way valves was fully utilized to develop a reasonable and efficient analysis process. Fully utilizing the hardware resources of the instrument, adopting a unique carbon dioxide filtration device, and adopting the on-demand analysis and cleaning technology, greatly facilitates the operation and application of the instrument.

Using multiple technical processing methods, analyze and determine the TMAX of different samples. The host adopts a large screen to display the operating status of the instrument, and at the same time, the computer displays the instrument operation chart and data processing function. Realize dynamic combination of host and computer.

The dual hydrogen flame ionization detector (FID) is organically combined with a nickel catalyst conversion device. Adopting an inner tank structure, the methane converter is directly mounted on the heating block of the detector, with nickel catalyst inside to convert the desorbed CO and CO2 in the absorption trap into methane, which enters the hydrogen flame ionization detector for detection. The absorption trap adopts a double cylindrical structure and is made of stainless steel material. The outer wall of the furnace body is processed into an arc-shaped groove, and the armored heating wire is tightly wound around the outer wall. It is equipped with ground molecular sieves inside to adsorb CO CO2， And desorb the adsorbed CO and CO2 at high temperatures.

The overall design of the instrument is innovative, unique, practical, stable, and reliable. The software is easy to operate and can meet the needs of on-site and laboratory analysis.
