CAS100 Carbon-14 Sampler

CAS100 Carbon-14 Sampler is designed with full-hardware structure, and consists of sampling pump, thermal mass flowmeter, time relay, catalytic oxidation bed of noble metal, temperature controller, bubbling absorption bottle, etc. It can simultaneously collect 2 samples, with independent circuits for organic carbon and inorganic carbon, and dual mass flow meters displaying inorganic carbon and organic carbon respectively. The device is equipped with protection design such as backflow and inversion prevention, which has high reliability and good adaptability. It can be used for a long time in high temperature, high humidity, and high salt fog environments.
