Short summary
In this work we describe a method to directly quantify water adsorption and mass hygroscopic growth of atmospheric particles as a function of RH at different temperature, using a commercial vapor sorption analyzer. We have demonstrated that this commercial instrument provides a simple, sensitive, and robust method to determine water adsorption and hygroscopicity of atmospheric particles.
