A novel device for analysis and detection of one or more gases or gas components of a gas mixture is disclosed. At least one gas sensor is installed in a capillary tube so that the target gas molecules diffuse through the tube length before affecti ng the said sensor and the transient response of the device to the target gas is mainly determined by the progress of the said diffusion process. The said transient response is then recorded and used as a measured value so that the target gas detecti on and diagnosis ensues from its comparison with the results of the previous experiences, calibration tests or mathematical simulations. More elaborate embodiments of the invented device include plurality of capillary tubes, each furnished with i ts respective gas sensor(s), forming an array or a bundle gas analyzer.
