| Abstract: | Trace gas analyzer based on integrated cavity output spectroscopy （ICOS） has been developed for gas sensing with the advantages of simple structure, easy maintenance, fast time response, high sensitivity and exact measurement. After introduced the principle of ICOS, the features and configuration of the analyzer were described. Laboratory and field experiments demonstrate that the analyzer has less than 1% linearity and long-term stability. A minimum detectable concentration is 250ppb for a 1,000 sweep average. |
| Keywords: | integrated cavity output spectroscopy high finesse cavity trace gas detection frequency modulation |
