Oxygen + Argon, Nitrogen, Methane and Carbon Monoxide - Determination of Non-Methane Total Hydrocarbon and Total Sulfur ContentOxygen + Argon, Nitrogen, Methane and Carbon Monoxide - Determination of Non-Methane Total Hydrocarbon and Total Sulfur Content
1. Analysis principle of oxygen, nitrogen and hydrogen analyzer
Oxygen, nitrogen and hydrogen in metal and non-metal solid materials are detected by inert gas fusion method.
Hydrogen can be divided into two types according to different methods:
1. Infrared absorption method for hydrogen measurement: When using infrared absorption method to measure hydrogen, a TC-306 oxygen, nitrogen and hydrogen analyzer can be used
The contents of oxygen, nitrogen and hydrogen were determined at the same time. The weighed sample was placed in a graphite crucible and heated in helium.
(When nitrogen is not measured, argon can be used to save costs) The sample is heated and melted in the air flow.
The carbon in the graphite crucible reacts to form carbon monoxide (CO), and the nitrogen and hydrogen in the sample are converted into nitrogen and hydrogen respectively.
The mixed gas is sent to the high temperature reformer by the carrier gas, where the carbon monoxide
(CO) is converted into carbon dioxide (CO2), H2 is converted into H2O, and nitrogen does not react.
The mixed gas is sent to the CO2 infrared detection cell and the H2O infrared detection cell.
The contents of carbon dioxide (CO2) and H2O can be used to calculate the contents of oxygen and hydrogen in the original sample.
After the carbon dioxide (CO2) and water in the mixed gas after infrared detection are adsorbed, the remaining nitrogen and
The helium mixed gas is detected by the thermal conductivity detection cell. The nitrogen is separated and then enters the thermal conductivity cell to detect the nitrogen content.
The test results are given directly after computer data processing. 
2. Thermal conductivity detection method for hydrogen measurement: When using the thermal conductivity detection method to measure hydrogen, only oxygen and nitrogen content or oxygen can be measured at one time.
Hydrogen content. Place the weighed sample in a graphite crucible and place it in a helium (argon can be used when nitrogen is not measured) atmosphere.
The oxygen in the sample reacts with the carbon in the graphite crucible to produce carbon monoxide.
(CO), the nitrogen in the sample escapes in the form of nitrogen (hydrogen in the form of hydrogen), and these mixed gases are carried by the carrier gas
There are two routes: one route is sent to a high temperature reformer, where carbon monoxide (CO) is converted into dioxygen
The mixed gas after passing through the reformer is sent to the CO2 infrared detection pool, where it is detected.
The content of carbon dioxide (CO2) is measured, and the oxygen content in the original sample is calculated based on it.
After the carbon dioxide (CO2) and water in the mixed gas after the warm reformer are adsorbed, the remaining nitrogen (or
Hydrogen) is detected through the thermal conductivity detection cell, and the test results are directly given after computer data processing
