NCS-CEMS VOCs Continuous Emission Monitoring System This instrument is provided with a two-way diaphragm pump with one way used for sampling the other for internal circulation of carrier gas. There is no need for carrier gas during the application process, which can greatly reduce the costs of operation and maintenance at the later stage. In the process of sampling, the sample is completely in the flow state, and there is no existence of dead volume. Upon the entry of analysis process, samples can be led by carrier gas into the chromatography and detector through the fast switching of gas...
