Rapid online analyzer for 14c-ams

A rapid online analyzer for 14C-AMS, comprising:

• a solid sample processing module:
• comprising an elemental analysis submodule and a CO2 purifying and collecting submodule, wherein the elemental analysis submodule is configured to convert a solid sample directly into CO2, the CO2 purifying and collecting submodule is configured to purify and collect CO2, and the solid sample is converted into CO2 via the elemental analysis submodule and then directly enters the CO2 purifying and collecting submodule;
• an atmospheric sample collecting and processing module:
• comprising an atmospheric sample collecting submodule and a CO2 purifying and storing submodule, wherein the atmospheric sample collecting submodule is configured to collect atmospheric samples at different heights in real time, the CO2 purifying and storing submodule is configured to purify and store CO2, and the atmospheric samples are collected via the atmospheric sample collecting submodule and then directly enter the CO2 purifying and storing submodule;
• a microflow control module:
• configured to perform microflow control of CO2 from the solid sample processing module and the atmospheric sample collecting and processing module, to keep a flow rate of CO2 at 10 μl/min or less;
• an AMS module:
• configured to lead out CO2→C− beam under Cs sputtering of CO2 from the microflow control module, and directly perform 14C-AMS determination of a gas sample;
• and
• an automatic control module:
• configured to control working processes of the solid sample processing module, the atmospheric sample collecting and processing module, and the microflow control module, and run in linkage with the AMS module.
