Abstract
We present a gas sensor system based on 245 GHz SiGe transmitter and receiver chips and a carbon molecular sieve gas concentrator. A gas mixture of 100 ppm methanol in ambient air at atmospheric pressure can be detected with high SNR of up to 430 at a pressure of 7.7 Pa after thermal desorption of the gas, which corresponds to a sensitivity of 230 ppb.
