Purpose of the development: To increase the sensor sensitivity. For the analysis of multicomponent mixtures with the presence of water molecules.

Recommended application field: Gas analysis systems. Sensor arrays for "Electronic nose".

Advantages over analogues: High sensitivity, simple implementation, low price. The observed effect opens up some additional perspectives for the analysis of multi-component mixtures with the presence of water molecules. This is particularly important for practical applications where the studied multicomponent mixtures include a number of water molecules.

The development stage readiness: Ready for application

Description of the development:
()
Nanoparticles were produced by reduction of the gold-chlor acid with the addition of sodium citrate. Gold nanoparticles obtained solution of citrate on QCM surface adsorption exhibit interesting properties with respect to water molecules. In contrast, low alcohols are adsorbed uniformly on the surface regardless of the presence or absence of nanoparticles thereon, the water adsorption process has a number of features. First of all, a review of sensors to water vapor in the order of magnitude of responses to alcohol - 1000 Hz.
