Can aerometers detect impurities in gases?

Aerometers are generally used to measure the density of gases or the concentration of particles in the air, not specifically to detect impurities. However, some types of gas analyzers or sensors can be used to detect impurities in gases. These devices are designed to measure the concentration of specific components or contaminants in a gas mixture, providing information about impurities.

For example:
* Gas Chromatographs separate and analyze compounds in a gas sample.
* Mass Spectrometers identify the types and quantities of molecules in a sample.
* Electrochemical Sensors can detect specific gases or pollutants.
* Infrared Sensors are used to identify gases based on their absorption of infrared light.
