Short summary
The paper describes a new technique for measuring the hygroscopic properties of laboratory and ambient aerosols. The direct measurements of humidified particle mass allow avoiding complications that occur in the commonly used technique due to poorly defined particle morphology and density. Both test results and field measurements have shown that the system can be applied for aerosol size-resolved mass growth factor measurements in hydration and dehydration modes up to 95 % RH.
