ternary composite gas sensor films are synthesized by a droplet pre-mixing transfer device. Synthesized gas sensor films are tested on a high throughput performance test instrument platform in ethanol atmosphere under programmed temperature cooling. The platform can quickly complete the process of " parallel material synthesis and high throughput screening"
which greatly improve the development efficiency of gas sensing materials. The maximum dynamic responses of 45 kinds of gas sensing films under the temperature program cooling are calculated. It is foun
d that the maximum dynamic response came from the 23 rd material( WO

whose dynamic response to the 50 × 10

ethanol is as high as-821. 5( p-type response). The experimental result shows the advantages of this equipment in the development of gas sensing materials.
