| Abstract: | In-situ gas monitoring system based on tunable diode laser absorption spectroscopy is use for analysis of gas concentration produced in the indructrial process.The monitoring system does not need the pretreatment of the sampled gas,has fast time response,escaped from the ground gas and grain,is adaptable to the horriable indructrial environment.The characteristic and machinery of the instrument will be introduced.So does the absorption spectroscopy and wavelength modulate techincs. |
